trajectoriesPolyFeatures {FRESA.CAD}

Extract the per patient polynomial Coefficients of a feature trayectory

Description

Given a longituinal data set, it will extract the associated polynomial coefficients for each sample.

Usage

	trajectoriesPolyFeatures(data,
                              feature="v1",
