majPara {warpMix}

Update the functional parameters (associated to the aligned curves).

Description

This function updates the estimations of the mean curve, the individual effect U_i, related to aligned curves.

Usage

majPara(t, y, splineBasisMu, splineBasisU, warpTime)

Arguments

t

A vector of numbers, corresponding to time points.

y

A matrix of numbers, corresponding to observations (size: T * n).

splineBasisMu

A matrix, corresponding to the spline basis for the global mean function, evaluted in time points.

splineBasisU

A matrix, corresponding to the spline basis for the individual curves, evaluted in time points.

warpTime

A matrix, corresponding to warping time points.

Value

A list, with x, aligned curves, alphaMu the coefficients of the mean curve, sigmaEpsilon the variance of the noise, sigmaU the variance of the random effects, and indSignal the individual curves.
