SAS/STAT offers a principled treatment of missing data in a frequentist paradigm. SAS' Michael Senter reveals how with a few code tweaks, you can seamlessly transition to a Bayesian analysis.
Many people have an intuitive feel for residuals in least square models and know that the sum of squared residuals is a goodness-of-fit measure. Generalized linear regression models use a different but related idea, called deviance residuals. What are deviance residuals, and how can you compute them? Deviance residuals (and
Circadian rhythms are natural internal biological processes that regulate the sleep-wake cycle and repeat roughly every 24 hours. These rhythms are influenced throughout the day by external cues like light and environmental temperature. Syncing our biological functions with the diurnal, day-to-night, fluctuations of the natural world around us plays a
