seizure: Epiliptic seizure counts from the Randomized Progabide Trial

In geesmv: Modified Variance Estimators for Generalized Estimating Equations

Description

The data consists of 59 subjects from the randomized progabide trial.

Usage

seizure

Format

• base:baseline epiliptic seizure counts

• trt:the indicator for treatment (1=progabide; 0=control)

• age:baseline age for each subject

• y1:epiliptic seizure counts in the first week

• y2:epiliptic seizure counts in the second week

• y3:epiliptic seizure counts in the third week

• y4:epiliptic seizure counts in the forth week

Details

The outcome is the count number of epiliptic seizures in each of four consecutive two-week intervals, and the variables recorded include baseline epiliptic seizure counts in an eight-week interval prior to the treatment assignment, the indicator for treatment (1=progabide; 0=control), and baseline age.
