After performing an ANOVA test, an analyst has determined that a significant effect exists due to income. The analyst wants to compare each Income to all others and wants to control for experimentwise error.
Which GLM procedure statement would provide the most appropriate output?
To compare each Income to all others and control for experimentwise error, the most appropriate GLM procedure would be to use the least squares means (lsmeans) with pairwise differences (pdiff) for all comparisons, adjusted using the Tukey method. The Tukey adjustment is specifically designed to control the experimentwise error rate when making multiple comparisons, providing a more robust statistical control. Therefore, 'lsmeans Income / pdiff=all adjust=tukey;' is the correct choice.
