Estimate Multiple Correlation Coefficients (R-Squared and Adjusted R-Squared) and Generate the Corresponding Sampling Distribution Using the Monte Carlo Method

Description

Estimate Multiple Correlation Coefficients (R-Squared and Adjusted R-Squared) and Generate the Corresponding Sampling Distribution Using the Monte Carlo Method

Usage

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


Arguments

 object Object of class mc, that is, the output of the MC() function. alpha Numeric vector. Significance level \alpha.

Details

R-squared (R^{2}) and adjusted R-squared (\bar{R}^{2}) are derived from each randomly generated vector of parameter estimates. Confidence intervals are generated by obtaining percentiles corresponding to 100(1 - \alpha)\% from the generated sampling distribution of R^{2} and \bar{R}^{2}, where \alpha is the significance level.

Value

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

call

Function call.

args

Function arguments.

thetahatstar

Sampling distribution of R^{2} and \bar{R}^{2}.

vcov

Sampling variance-covariance matrix of R^{2} and \bar{R}^{2}.

est

Vector of estimated R^{2} and \bar{R}^{2}.

fun

Function used ("RSqMC").
