OCR: Lenth's Pseudo Standard Error (PSE) In experiments with large number of effects, , it is expected that most of the effects are zero Because there is usually not much le to estimate error with the distribution of the parameter estimate is used to estimate their standard error. This estimate called the pseudo standard error, is 1.5 times the median absolute value of estimates after removing all estimates greater than 3.75 times median absolute estimate in the complete set estimates. It use normalized estimates because if depends on them being uncorre and having equal variancs.
