In DrrDom/pfpp: Different convenience functions (file loading, caret model processing, etc)

Determination coefficient for external test set or cross-validation.

Description

Returns determination coefficient for external test set or cross-validation.

Usage

R2test(ts.pred, ts.obs, ws.obs.mean = mean(ts.obs))

Arguments

ts.pred	predicted values for external test set or cross-validation folds.
ts.obs	observed values for external test set or cross-validation folds.
ws.obs.mean	mean value for training set. If determination coefficient for cross-validation folds is calculated, then this parameter can be left as is.

Value

value of determination coefficient calculated according to formula 1-PRESS/SS.

Examples

set.seed(42)
cv.obs <- runif(50, 0, 10)
cv.pred <- cv.obs + rnorm(50)
R2test(cv.pred, cv.obs)
