When using survey data (with clustering and stratification), what are the recommended approaches to estimate a statistic which is not estimated by the SAS survey procs? For example, a confidence interval for the ratio of the mean of variable 1 to the standard deviation of variable 2. Can the survey procs be tweaked for this? Any pointers to a replication (bootstrap or jackknife) approach?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
