simMatrix: Create simMatrix that save free parameters and starting values, as well as fixed values

Description

Create SimMatrix object that save free parameters and starting values, as well as fixed values. This will be used for model specification later, such as for factor loading matrix or regression coefficient matrix.

Usage

simMatrix(free = NULL, value = NULL)

Arguments

free

Matrix of free parameters. Use NA to specify free parameters. Use number as fixed value (including zero). If this argument is not specified, the information from the value argument is used. The positions in the value

value

Starting values. Can be either one element or matrix with the same dimension as free parameter matrix. Each element can be numbers (in either as.numeric or as.character format) or the name of distribution object

Value

• SimMatrix object that will be used for model specification later.

Examples

loading <- matrix(0, 6, 2)
loading[1:3, 1] <- NA
loading[4:6, 2] <- NA
loadingValues <- matrix(0, 6, 2)
loadingValues[1:3, 1] <- 0.7
loadingValues[4:6, 2] <- 0.7
LX <- simMatrix(loading, loadingValues)
summary(LX)
run(LX)

n65 <- simNorm(0.6, 0.05)
LY <- simMatrix(loading, "n65")
summary(LY)
run(LY)

start <- matrix(0, 6, 2)
start[1:3, 1] <- 0.7
start[4:6, 2] <- 0.7
ST <- simMatrix(value=start)
