In cbsem: Simulation, Estimation and Segmentation of Composite Based Structural Equation Models

Description

NewtonFl Newton's method to find roots of the function FlFunc.

Usage

NewtonFl(target, startv, maxIter = 100, converge = 1e-12)

Arguments

target	vector with the desired skewness and kurtosis
startv	vector with initial guess of the coefficents for the Fleishman transform
maxIter	maximum of iterations
converge	limit of allowed absolute error

Value

out list with components

coefficients	vector with the approximation to the root
value	vector with differences of root and target
iter	number of iterations used

Examples

skew <- 1; kurt <- 2
startv <- c( 0.90475830, 0.14721082, 0.02386092)  
out <- NewtonFl(c(skew,kurt),startv)
