Abstract

Meyners, M., Carr, B. T., & Kunert, J. (2023). Equivalence and non-inferiority tests using replicated discrimination and preference data. Journal of Sensory Studies, 38(6), e12882. https://doi.org/10.1111/joss.12882

In the originally published version, an error was unfortunately introduced in the final processing of the article. On page 11, the R code to determine sample sizes for the one-sided test scenario needs to read as follows (correcting the function used in the definition of pwr):

simple.sample.size <- function(power=0.8, k, p0, pd,

pdtrue=0, alpha=0.05){

pwr <- 0

n <- 0

while(pwr < power){

 n <- n + 1

  pwr <- simple.power(n, k, p0,

                 pd, pdtrue, alpha) }

return(n) }

The online version of this article has been corrected accordingly.

We apologize for any inconvenience caused.
