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

Description

This function initializes the mean curve, the individual effect U_i, related to aligned curves.

Usage

initialisationPara(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 each individual curves.
