timeSplitter

An object created using createStudyPopulation().

population

A real number between 0 and 1 indicating the test set fraction of the data

test

A real number between 0 and 1 indicating the training set fraction of the data

train

An integer &gt;= 1 specifying the number of folds used in cross validation

nfold

If set a fixed seed is used, otherwise a random split is performed

seed

Split test/train data by time and then partitions training set into random folds stratified by
class

A package for creating patient level prediction models. Given a
cohort of interest and an outcome of interest, the package can use data in the
OMOP Common Data Model to build a large set of features. These features can then
be assessed to fit a predictive model using a number of machine learning algorithms.
Several performance measures are implemented for model evaluation.
