Precision follows the decision: how well an acceptance probability is known for mean-spread release rules
Remus Osan
Many release rules accept a lot when a statistic built from the sample mean and standard deviation stays within a limit, and the probability that a process passes such a rule can b…
Closed forms all the way up: the sample variance of four observations
Remus Osan
The distribution function of the sample variance of four independent observations is elementary on its entire support for every polynomial parent density…
Closed forms and open obstructions: the sample variance of three observations
Remus Osan, Kevin T. Chu, Ron Yu
The exact distribution of the sample variance for is known since Rietz (1931) for the uniform parent, and Royen (2007, 2008) gave a Fourier series for any bounded continuous…
Phasing out Monte Carlo: exact acceptance probabilities for mean-spread release rules
Remus Osan
A large family of regulated release decisions accepts a production lot if and only if the pair (sample mean, sample standard deviation) of units falls in a fixed plane region.…
