d_attenuation: Calculate the Cohen's D after attenuation based on Spearman's...

In mathesong/relfeas: Reliability for Feasibility Analysis

Description

Enter in only one effect size measure

Usage

d_attenuation(rel_total = NULL, rel_onegroup = NULL, d = NULL,
  overlap = NULL, u3 = NULL, cles = NULL, n1 = 10, n2 = n1)

Arguments

rel_total	Reliability or reliabilities for the total combined sample of measurements
rel_onegroup	Reliability or reliabilities for one group of measurements.
d	True Cohen's D of biological signal before accounting for measurement error
overlap	True distributional overlap of biological signal before accounting for measurement error
u3	True Cohen's U3 of biological signal before accounting for measurement error
cles	True CLES of biological signal before accounting for measurement error
n1	Number of measurements in group 1. Optional: only required if group sizes differ.
n2	Number of measurements in group 2. Optional: only required if group sizes differ.

Value

The Cohen's D after attenuation

Examples

d_attenuation(rel_total = 0.7, u3=0.9)
d_attenuation(rel_onegroup = 0.7, u3=0.9)
