PCorNB {betaNB}

Estimate Squared Partial Correlation Coefficients and Generate the Corresponding Sampling Distribution Using Nonparametric Bootstrapping

Description

Estimate Squared Partial Correlation Coefficients and Generate the Corresponding Sampling Distribution Using Nonparametric Bootstrapping

Usage

PCorNB(object, alpha = c(0.05, 0.01, 0.001))

Arguments

object

Object of class nb, that is, the output of the NB() function.

alpha

Numeric vector. Significance level \alpha.

Details

The vector of squared partial correlation coefficients (r^{2}_{p}) is estimated from bootstrap samples. Confidence intervals are generated by obtaining percentiles corresponding to 100(1 - \alpha)\% from the generated sampling distribution of r^{2}_{p}, where \alpha is the significance level.

Value

Returns an object of class betanb which is a list with the following elements:

call

Function call.

args

Function arguments.

thetahatstar

Sampling distribution of r^{2}_{p}.

vcov

Sampling variance-covariance matrix of r^{2}_{p}.

est

Vector of estimated r^{2}_{p}.

fun

Function used ("PCorNB").
