plot_ff_coeffs {robflreg}

Image plot of bivariate regression coefficient functions of a function-on-function regression model

Description

This function is used to obtain image plots of bivariate regression coefficient functions of a function-on-function regression model based on output object obtained from get.ff.coeffs.

Usage

plot_ff_coeffs(object, b)

Arguments

object

The output object of get.ff.coeffs.

b

An integer value indicating which regression parameter function to be plotted.

Value

No return value, called for side effects.

Examples

sim.data <- generate.ff.data(n.pred = 5, n.curve = 200, n.gp = 101)
Y <- sim.data$Y
X <- sim.data$X
gpY = seq(0, 1, length.out = 101) # grid points of Y
gpX <- rep(list(seq(0, 1, length.out = 101)), 5) # grid points of Xs
model.fit <- rob.ff.reg(Y, X, model = "full", emodel = "classical", 
                        gpY = gpY, gpX = gpX)
coefs <- get.ff.coeffs(model.fit)
plot_ff_coeffs(object = coefs, b = 1)
