## What is StatsNoisy?

Noisy is a professional-grade analytical tool designed for investment professionals and finance enthusiasts who need to separate true investment skill from market "noise."

Redesigned from the ground up with a premium SwiftUI interface, Noisy provides interactive visualizations and rigorous statistical modeling to help you understand the relationship between Alpha, Tracking Risk, and the Information Ratio.

FEATURES:

• DUAL-PATH ANALYSIS:
  - Information Ratio: Explore how specific skill levels scale with risk to determine "Implied Alpha" targets.
  - Tracking Risk: Model the "Luck Factor"—see the probability of outperforming benchmark targets with zero skill (IR=0).

• ADVANCED VISUALIZATIONS:
  - Dynamic Probability Density (PDF) charts with dual markers.
  - Red markers indicate your performance hurdles or targets.
  - Green markers highlight the expected value (Benchmark).
  - "Nice Ticks" axis algorithm ensures clean, readable labels (5%, 10%, 25%) without the clutter.

• MULTI-MANAGER MODELING:
  - Simulate the performance of up to 100 managers simultaneously.
  - View Probability Mass Functions (PMF) to understand the likelihood of "At least one" manager outperforming.

• EDUCATIONAL HUB:
  - In-depth definitions and assumptions built directly into the app.
  - Learn core concepts like Active Risk, Alpha, and the Square Root of Time rule.

Perfect for Portfolio Managers, Risk Analysts, and CFA® candidates, Noisy brings institutional-quality performance modeling to your iPhone.
