R: Functional Linear Model Analysis

flm_cate

R Documentation

Functional Linear Model Analysis

Description

A function that does functional linear model analysis.

Usage

flm_cate(FD, basistype="fourier", nbasis=9, norder=4)

Arguments

`FD`	The list from the function `fda.smoothdata`.
`basistype`	A string specifying either `"fourier"` and `"bspline"`.
`nbasis`	The number of basis functions to be used for functional linear model analysis. Default value is 9.
`norder`	an integer specifying the order of b-splines, which is one higher than their degree. The default of 4 gives cubic splines.

Value

A list consisting of three components as follows:

`freg`	A `fRegress` fit object containing the intercept and coefficient functions (check function `fRegress` for details)
`fregstd`	A list containing the standard error functions of the intercept and coefficient functions.

Examples

	data(act_29pt)
	data(clinic_29pt_ahi)
	
	colnames(act_29pt) <- sub("X", "", colnames(act_29pt)) 
	data <- as.matrix(act_29pt[,-1])
	
	matchid  <- fda.matchid(data, clinic_29pt_ahi, "contin")
	FDcont <- fda.smoothdata(matchid)
	
	geftFDcont <- flm_cate(FDcont)
