These data arise from a study of analgesic effects of treatments of elderly patients who have neuralgia. Two treatments and a placebo are compared. The response variable is whether the patient reported pain or not. Researchers recorded the age and gender of 60 patients along with the duration of complaint before the treatment began.
A data frame with 60 observations and 5 variables:
Factor with 3 levels
The latter is placebo
Factor with two levels
Numeric covariate – patient's age in years
Numeric covariate – duration of the condition before beginning treatment
Binary response factor with levels

# Model and analysis shown in the SAS report: neuralgia.glm <- glm(Pain ~ Treatment * Sex + Age, family = binomial(), data = neuralgia) pairs(emmeans(neuralgia.glm, ~ Treatment, at = list(Sex = "F")), reverse = TRUE, type = "response", adjust = "bonferroni")
