  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by OpenSenseNova on GitHub. Read the source before you install it.

Installation

Install the Statistical Distribution And Outlier Analysis AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/OpenSenseNova/SenseNova-Skills.git /tmp/SenseNova-Skills
mkdir -p .claude/skills
cp -r /tmp/SenseNova-Skills/skills/sn-da-excel-workflow/capability/excel-data-visualization/histogram-visualization .claude/skills/statistical-distribution-and-outlier-analysis
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Statistical Distribution And Outlier Analysis in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Statistical Distribution And Outlier Analysis on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Statistical Distribution And Outlier Analysis is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Step 1 加载数据并进行预处理,配置中文字体与环境参数

python
import pandas as pd
import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns
import re

# 设置中文字体,兼容不同环境
plt.rcParams['font.sans-serif'] = ['SimHei', 'WenQuanYi Zen Hei', 'DejaVu Sans']
plt.rcParams['axes.unicode_minus'] = False

# 加载数据并处理合并单元格
file_path = 'input_data.xlsx'
df = pd.read_excel(file_path)
df.ffill(inplace=True) # 处理可能的合并单元格空值

# 统一重命名列名以便于程序化处理
original_columns = df.columns.tolist()
df.columns = [f'col_{i+1}' for i in range(df.shape[1])]

print(f"数据形状: {df.shape}")
print(f"原始列映射: {dict(zip(df.columns, original_columns))}")

Step 2 生成多子图箱线图,直观展示各维度数据的分布特征与统计量

python
# 计算子图布局
num_cols = len(df.columns)
rows = (num_cols + 2) // 3
fig, axes = plt.subplots(rows, 3, figsize=(18, 5 * rows))
fig.suptitle('数据分布维度分析', fontsize=16, fontweight='bold')
axes_flat = axes.flatten()

for i, column in enumerate(df.columns):
    data_series = df[column].dropna()
    if pd.api.types.is_numeric_dtype(data_series):
        axes_flat[i].boxplot(data_series, patch_artist=True,
                            boxprops=dict(facecolor='lightblue', alpha=0.7),
                            medianprops=dict(color='red', linewidth=2))
        
        stats = data_series.describe()
        axes_flat[i].set_title(f'{column} (n={len(data_series)})', fontsize=12)
        axes_flat[i].text(0.05, 0.95, f'均值: {stats["mean"]:.2f}\n中位数: {stats["50%"]:.2f}',
                         transform=axes_flat[i].transAxes, verticalalignment='top',
                         bbox=dict(boxstyle='round', facecolor='white', alpha=0.8))
    axes_flat[i].grid(True, alpha=0.3)

plt.tight_layout(rect=[0, 0.03, 1, 0.95])
output_path = 'individual_boxplots.png'
plt.savefig(output_path, dpi=300, bbox_inches='tight')
plt.show()

Step 3 执行异常值检测算法,计算四分位距(IQR)并生成统计报告

python
analysis_results = []

for col in df.columns:
    data = df[col].dropna()
    if not pd.api.types.is_numeric_dtype(data):
        continue
        
    Q1 = data.quantile(0.25)
    Q3 = data.quantile(0.75)
    IQR = Q3 - Q1
    lower_bound = Q1 - 1.5 * IQR
    upper_bound = Q3 + 1.5 * IQR
    
    outliers = data[(data < lower_bound) | (data > upper_bound)]
    
    analysis_results.append({
        '维度': col,
        '样本量': len(data),
        '异常值数量': len(outliers),
        '偏度': round(data.skew(), 3),
        '峰度': round(data.kurtosis(), 3),
        '范围': f"{data.min():.2f} ~ {data.max():.2f}"
    })

report_df = pd.DataFrame(analysis_results)
print("=== 数据质量与分布报告 ===")
print(report_df.to_string(index=False))

Step 4 使用正则表达式从文本列中提取误差值(±模式)并进行量化分析

python
# 假设 target_col 包含类似 "10.5 ± 0.2" 的文本
target_col = df.columns[0] 
text_data = df[target_col].astype(str).str.cat(sep=' ')

# 正则表达式提取 ± 后面的数值
error_pattern = r'±(\d+\.?\d*)'
extracted_errors = [float(val) for val in re.findall(error_pattern, text_data)]

if extracted_errors:
    print(f"提取到误差样本量: {len(extracted_errors)}")
    print(f"误差均值: {np.mean(extracted_errors):.4f}")
else:
    print("未在指定列中检测到符合 ± 模式的误差数据")

Step 5 绘制误差分布直方图,并标注核心统计参考线

python
if extracted_errors:
    plt.figure(figsize=(10, 6))
    # 自动计算 bins 数量
    n, bins, patches = plt.hist(extracted_errors, bins='auto', color='skyblue', 
                                edgecolor='black', alpha=0.7)
    
    # 在柱体上方标注频次
    for i in range(len(n)):
        if n[i] > 0:
            plt.text(bins[i] + (bins[i+1]-bins[i])/2, n[i] + 0.1, 
                    str(int(n[i])), ha='center', va='bottom', fontweight='bold')

    # 添加均值参考线
    mean_val = np.mean(extracted_errors)
    plt.axvline(mean_val, color='red', linestyle='--', linewidth=2, 
                label=f'误差均值: {mean_val:.3f}')
    
    plt.title('误差项分布特征直方图', fontsize=14)
    plt.xlabel('误差量级', fontsize=12)
    plt.ylabel('出现频次', fontsize=12)
    plt.legend()
    plt.grid(axis='y', alpha=0.3)
    
    plt.tight_layout()
    plt.savefig('error_distribution_histogram.png', dpi=300)
    plt.show()

Step 6 导出分析摘要并生成下载链接

python
summary_file = 'analysis_summary.csv'
report_df.to_csv(summary_file, index=False, encoding='utf_8_sig')

from IPython.display import FileLink
print("分析完成,点击下方链接下载报告:")
display(FileLink(summary_file))
display(FileLink('individual_boxplots.png'))

Frequently asked questions

What does the Statistical Distribution And Outlier Analysis AI skill do?

执行数值型数据的分布分析与异常值检测,支持通过正则表达式从文本中提取误差项并生成高分辨率的箱线图与直方图报告。

Why use Statistical Distribution And Outlier Analysis on TypingMind?

Because you install it once and use it with any model. Statistical Distribution And Outlier Analysis is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Statistical Distribution And Outlier Analysis in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/OpenSenseNova/SenseNova-Skills/tree/main/skills/sn-da-excel-workflow/capability/excel-data-visualization/histogram-visualization. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Statistical Distribution And Outlier Analysis?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Statistical Distribution And Outlier Analysis?

As many as you like. As long as a model supports skills, you can use Statistical Distribution And Outlier Analysis with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Statistical Distribution And Outlier Analysis AI skill free?

Yes. It is published on GitHub by OpenSenseNova under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
