Description Usage Arguments Value Examples
Calculate the extrapolated reliability for a given standard deviation value
1 | sd2extrapRel(sd, icc_original, sd_original = 1, tau = 1)
|
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. |
The extrapolated ICC ICC value for the new sample
1 | sd2extrapRel(sd=2, icc_original=0.5)
