# promin: Promin rotation In PCovR: Principal Covariates Regression

## Description

This is a rotation criterion, developed by Lorenzo-Seva (1999), in which oblique target rotation (`tarrotob`) is applied using the Weighted Varimax solution (`wvarim`) as the target matrix.

## Usage

 `1` ```promin(F1, nrs = 20) ```

## Arguments

 `F1` Matrix to be rotated `nrs` Number of random starts

## Value

 `Th ` Transformation matrix to the pattern `loadings ` Rotated matrix `U` Transformation matrix to the structure
