Comparison of Length-Frequency Analyses for Estimation of

Tests Treat samples made up of observations from several different populations Can treat data which are inherently in ranks as well as data whose seemingly numerical scores have the strength in ranks They are available to treat data which are classificatory Easier to learn and apply than parametric tests

Comparison of Length-Frequency Analyses for Estimation of

Performing Exact Logistic Regression with the SAS System

Many clinical trials deal with the comparison of populations of subjects with categorical responses Historically, statisti-cal inference for such studies involved large-sample approximations, and ﬁtting logistic regression models to such data was performed through the unconditional likelihood function
