TIMESLICE CROSS VALIDATION CARET HOW TO

This number depends on the CV method that you are using. Divide the dataset into two parts: one for training, other for testing.split and split<- are generic functions with default and data. The value returned from split is a list of vectors containing the values for the groups. split divides the data in the vector x into the groups defined by f. The caret package (short for Classification And REgression Training) contains functions to streamline the model training process for complex regression and classification problems. groupKFold splits the data based on a grouping factor. createFolds splits the data into k groups while createTimeSlices creates cross-validation split for series data. What is the purpose of function createDataPartition?Ī series of test/training partitions are created using createDataPartition while createResample creates one or more bootstrap samples. If the y argument to this function is a factor, the random sampling occurs within each class and should preserve the overall class distribution of the data. The function createDataPartition can be used to create balanced splits of the data.
