# PSR

Partial-sample regression function to estimate the similarity, informativeness, and relevance of dependent variables.

## Description

Estimate results from the partial-sample regression model as described by Czasonis, Kritzman, and Turkington in their 2020 research paper (Journal of Portfolio Management, see reference link below).

One of our principals, Mark Kritzman, introduces this powerful model in a lecture at State Street's research retreat in 2020. View a recording on the lecture below.
