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

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

# NOT RUN {
skew <- 1; kurt <- 2
startv <- c( 0.90475830, 0.14721082, 0.02386092)  
out <- NewtonFl(c(skew,kurt),startv) 

# }
