covariateData |
An object as generated using the |
minFraction |
Minimum fraction of the population that should have a non-zero value for a covariate for that covariate to be kept. Set to 0 to don't filter on frequency. |
normalize |
Normalize the covariates? (dividing by the max). |
removeRedundancy |
Should redundant covariates be removed? |
Normalize covariate values by dividing by the max and/or remove redundant covariates and/or remove infrequent covariates. For temporal covariates, redundancy is evaluated per time ID.
