Description

Estimates alpha and beta parameter with Newton Raphson method by J.N.K. Rao

Usage

newtonRaphsonR(data.dir, pcap, maxiter, tol)

Arguments

data.dir

Direct estimates of the data from function pcapdir

pcap

weighted sample mean and variance from function pcapdir

maxiter

the Maximum iteration value

tol

Tolerance error value in iteration

Value

This function returns a data frame with following objects :

alpha_cap

an alpha estimator by Newton Raphson method of J.N.K.Rao

beta_cap

an beta estimator by Newton Raphson method of J.N.K.Rao

Examples

## load dataset with no weight value
data(dataEB)
temp = pcapdir(dataEB[,-c(3)])
newtonRaphsonR(data.dir = temp$direst, pcap = temp$pcap,
 maxiter = 100, tol = 0.00001)

##load dataset with weight value
data(dataEB)
temp = pcapdir(dataEB)
newtonRaphsonR(data.dir = temp$direst, pcap = temp$pcap,
 maxiter = 100, tol = 0.00001)
