Recovery is a proportion between 0 and 1. Linear regression can predict values outside this range ($>100%$). models the log-odds of recovery: Statistical Methods For Mineral Engineers
The book's primary strength is its , specifically bridging the gap between theoretical statistics and the messy reality of mine site data.
