estimationTheta: Estimate the warping parameters.

In warpMix: Mixed Effects Modeling with Warping for Functional Data Using B-Spline

Description

This function estimate the warping parameters, knowing the observations and the individual aligned curves.

Usage

estimationTheta(t, y, splineBasisW, indSignal, thetaObs)

Arguments

t	A vector of numbers, corresponding to time points.
y	A matrix of numbers, corresponding to observations (size: T * n).
splineBasisW	A matrix, corresponding to the spline basis for the warping functions, evaluted in time points.
indSignal	A matrix, corresponding to the individual aligned curves.
thetaObs	A matrix, corresponding to initial values for the warping parameters.

Value

A list, with theta, a matrix of estimated warping parameters, and wT, the corresponding warping functions.
