corrSim {NCStats}R Documentation

Dynamic simulations to demonstrate how the correlation is computed.

Description

This function simulates bivariate data with a known correlation coefficient. A crosshairs at the bivariate means and color coding of the product of standardized values helps illustrate how the concept of the correlation. Optionally, rectangles from each point to the bivariate mean can be include to demonstrate how the correlation sums these areas (concept from cor.rect.plot).

Usage

corrSim()

Details
