In ppsr: Predictive Power Score

Description

Calculate out-of-sample model performance of naive baseline model The calculation that's being performed depends on the type of model For regression models, the mean is used as prediction For classification, a model predicting random values and a model predicting modal values are used and the best model is taken as baseline score

Usage

Arguments

train	df, training data, containing variable y
test	df, test data, containing variable y
x	character, column name of predictor variable
y	character, column name of target variable
type	character, type of model
metric	character, evaluation metric being used

Value

numeric vector of length one, evaluation score for predictions using naive model
