sim_model_ex2: Function for generating functional data in one or multiple dimension

Description

The function can generate one-dimensional or multi-dimensional curves. For i_sim 1 or 2, one-dimensional curves are generated. For i_sim 3 or 4, multi-dimensional curves are generated.

Usage

sim_model_ex2(n = 50, p = 150, i_sim = 1)

Value

data matrix of size \(2n \times p\) if \(i\_sim \in {1,2}\)

or an array of dimensions \(2n \times p \times 2\) if \(i\_sim \in {3, 4}\).

Arguments

n

Number of curves to generate for each of the two groups. Set to 50 by default.

p

Number of grid points of the curves. Curves are generated over the interval \([0, 1]\). Set to 150 grid point by default.

i_sim

Integer set to \(1, \ldots, 4\) NULL by default in which case a seed is not set.

Examples

sm1 <- sim_model_ex2()
dim(sm1) # This should output (100, 150) by default, since n = 50 and p = 150

sm4 <- sim_model_ex2(i_sim = 4)
dim(sm4) # This should output (100, 150, 2) by default, since n = 50 and p = 150
