.fungible_extrema: Locate extrema of fungible OLS regression weights

Description

Locate extrema of fungible OLS regression weights

Usage

.fungible_extrema(
  theta,
  Rxx,
  rxy,
  Nstarts = 1000,
  MaxMin = c("min", "max"),
  silent = FALSE
)

Value

A list containing the alternative weights and other fungible weights estimation parameters

Arguments

theta

The value of the R-squared decrement used to generate a family of fungible coefficients.

Rxx

An intercorrelation matrix among the predictor variables

rxy

A vector of predictor–criterion correlations

Nstarts

The maximum number

MaxMin

Should the cosine between the OLS and alternative weights be maximized ("max") to find the maximally similar coefficients or minimized ("min") to find the maximally dissimilar coefficients?

silent

Should current optimization values be printed to the console (FALSE) or suppressed (TRUE)?
