estimationTheta {warpMix}

Estimate the warping parameters.

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.
