In ck37/ckTools: Chris Kennedy's R Toolkit

Calculate RMSE from cross-validation results

Description

Calculate RMSE from cross-validation results

Usage

rmse(preds, actual, test_folds, version = 1)

Arguments

preds	Predicted values or score
actual	Known value
test_folds	Length n vector assigning each vector to a given test fold
version	1 (default) or 2. 1 averages the RMSE over folds; 2 averages the MSE and then takes the square root.

Value

Dataframe of results, including RMSE, standard error, and CI
