Conservative Dual Criteria (CDC) desired zone below lines

Description

The conservative dual-criteria (CDC) is a relatively new approach to comparing phases that works well when data have a moderate lag-1 autocorrelation (lower than 0.6). This function uses two lines to define the desired zone: the mean and the regression line of the comparison phase.

Usage

CDCbelow(behavior, phaseX, v1, v2)

Arguments

behavior

behavior variable

phaseX

phase variable

v1

phase letter of first (i.e., comparison) phase between quotation marks (e.g., "A")

v2

phase letter of second phase between quotation marks (e.g., "B")
