Description Usage Arguments Value Examples

View source: R/converters.R

Description

Calculate the extrapolated reliability for a given standard deviation value

Usage

1
sd2extrapRel(sd, icc_original, sd_original = 1, tau = 1)

Arguments

sd

Standard deviation in the new sample for which the reliability is being extrapolated.

icc_original

ICC from the original study.

sd_original

Standard deviation from the original study. Optional: default is 1. For 1, the sd argument is the proportional increase in SD.

tau

SEM inflation factor. Optional: default is 1. For 1, the SEM is assumed to be constant between studies.

Value

The extrapolated ICC ICC value for the new sample

Examples

1
sd2extrapRel(sd=2, icc_original=0.5)
