Scenario Lab: A Powerful Scenario Analysis Tool
{% endembed %}

It relies on a powerful statistic called the Mahalanobis distance to determine the likelihood of prospective economic scenarios.  This statistic was originally derived in the early 20th century by an Indian mathematician to analyze human skulls, and it has since been applied to measure turbulence in the financial markets, diagnose diseases, detect anomalies in self-driving vehicles, and construct an index of the business cycle.

**Scenario Lab** supports all the steps of scenario analysis.

### Features

* Generates pre-defined or customized economic scenarios<br>
* Assigns probabilities to economic scenarios by measuring their statistical similarity to current economic conditions or average economic conditions for a chosen history<br>
* Shows how to modify scenario specifications to reconcile empirically driven scenario probabilities with an investors' subjective views<br>
* Maps prospective economic scenarios onto asset class returns<br>
* Generates a variety of portfolio metrics for determining the most suitable portfolio&#x20;

### Scenario Lab Innovations

* Replaces guesswork of assigning probabilities to prospective scenarios with a mathematically rigorous algorithm for measuring statistical similarity<br>
* Enables investors to evaluate portfolio risk and return
