R-square
Let’s say we want to determine if Y (continuous) could be predicted by other metrics (X1, X2, X3-all continuous).
We have table with 31 rows, each row contains data about X1, X2, X3 & Y.
We want to find out what are the metrics we should use as inputs to Y while we want to account for at least 81% of the variation in Y.
We fit the model and looked at the "summary of fit", there we see R-square of ...
