H. Alex Yu Park Ranger of National Bootstrap Forest What not regression? OLS regression is good for small-sample analysis. If you have an extremely large sample (e.g. Archival data), the power level may aproach 1 (.99999, but it cannot be 1). and Regress Decision Tree. KH Wong. Decision tree v3.(230403b). 1.

A Decision Tree is a supervised learning strategy in machine learning. It may be used with both classification and regression algorithms. . As the name says, it resembles a tree with nodes. The branches are determined by the number of criteria. It separates data into these branches until a threshold unit is reached. .
