makeV: Design matrix for random effects in FDSLRM

In gajdosandrej/fdslrm: R package for modeling and prediction of time series using linear mixed models

Description

makeV(times, freqs) creates a design matrix V for random effects (including an intercept) in FDSLRM (for each frequency f produces two columns of V: sin(2*π*f*times), cos(2*π*f*times). makeV is a special case of makeF except for the first column of 1 for the intercept.

Usage

makeV(times, freqs)

Arguments

times	vector of observation times.
freqs	vector of (Fourier) frequencies.

Value

Design matrix V for random effects in FDSLRM.

Examples

## EXAMPLE 1
times <- c(1:24)
frequencies <- c(1/12, 1/8)
matV <- makeV(times, frequencies)
print(matV)
