Data science and analytics expertise for statistical analysis, machine learning pipelines, data governance, business intelligence, predictive modeling, and analytics strategy. Use when building ML models, analyzing data, creating dashboards, or designing data architectures.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Data Science Expert

Comprehensive data science frameworks for analytics, machine learning, and data-driven decision making.

## Data Strategy

### Data Maturity Model

| Level | Name                | Characteristics                           |
| ----- | ------------------- | ----------------------------------------- |
| 1     | **Ad Hoc**          | Manual, inconsistent, siloed              |
| 2     | **Opportunistic**   | Some automation, point solutions          |
| 3     | **Systematic**      | Defined processes, governance emerging    |
| 4     | **Differentiating** | Data-driven decisions, advanced analytics |
| 5     | **Transformative**  | AI-first, competitive advantage           |

### Analytics Value Chain

```
DATA → INFORMATION → INSIGHT → ACTION → VALUE

PROGRESSION:
Descriptive: What happened?
Diagnostic: Why did it happen?
Predictive: What will happen?
Prescriptive: What should we do?
Autonomous: Self-optimizing systems
```

## Statistical Analysis

### Descriptive Statistics

```
CENTRAL TENDENCY:
- Mean: Sum / Count (sensitive to outliers)
- Median: Middle value (robust to outliers)
- Mode: Most frequent value

DISPERSION:
- Range: Max - Min

How to install

The exact contents, by fingerprint

mdr add travisjneuman/.claude/data-science@sha256:85f0a59aef37391b

The line at the top of this page pins the label git:20260930.c8d311d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
