yhat: Wrap Various Predict Functions

In DALEX: moDel Agnostic Language for Exploration and eXplanation

Wrap Various Predict Functions

Description

This function is a wrapper over various predict functions for different models and differnt model structures. The wrapper returns a single numeric score for each new observation. To do this it uses different extraction techniques for models from different classes, like for classification random forest is forces the output to be probabilities not classes itself.

Usage

yhat(X.model, newdata, ...)

## S3 method for class 'lm'
yhat(X.model, newdata, ...)

## S3 method for class 'randomForest'
yhat(X.model, newdata, ...)

## S3 method for class 'svm'
yhat(X.model, newdata, ...)

## S3 method for class 'gbm'
yhat(X.model, newdata, ...)

## S3 method for class 'glm'
yhat(X.model, newdata, ...)

## S3 method for class 'cv.glmnet'
yhat(X.model, newdata, ...)

## S3 method for class 'glmnet'
yhat(X.model, newdata, ...)

## S3 method for class 'ranger'
yhat(X.model, newdata, ...)

## S3 method for class 'model_fit'
yhat(X.model, newdata, ...)

## S3 method for class 'train'
yhat(X.model, newdata, ...)

## S3 method for class 'lrm'
yhat(X.model, newdata, ...)

## S3 method for class 'rpart'
yhat(X.model, newdata, ...)

## S3 method for class ''function''
yhat(X.model, newdata, ...)

## S3 method for class 'party'
yhat(X.model, newdata, ...)

## Default S3 method:
yhat(X.model, newdata, ...)
