emmeans (version 1.4.8)

neuralgia: Neuralgia data

Description

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.

Usage

neuralgia

Format

A data frame with 60 observations and 5 variables:

Treatment

Sex

Age

Numeric covariate -- patient's age in years

Duration

Numeric covariate -- duration of the condition before beginning treatment

Pain

Binary response factor with levels No and Yes

Examples

# NOT RUN {
# 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")

# }
