Description: For general linear models with normally distributed random errors, the probability of a Type II error decreases exponentially as a function of sample size. This potentially rapid decline reemphasizes the importance of performing power calculations.

Keywords: Power, sample size, linear models, experimental design, noncentral F, normal tail, Mills’ ratio, asymptotic relative efficiency, Hodges-Lehmann efficiency, Pitman efficiency, minimum detectable difference
