On this Picostat.com statistics page, you will find information about the cgd data set which pertains to Chronic Granulotomous Disease data. The cgd data set is found in the survival R package. You can load the cgd data set in R by issuing the following command at the console data("cgd"). This will load the data into a variable called cgd. If R says the cgd data set is not found, you can try installing the package by issuing this command install.packages("survival") and then attempt to reload the data. If you need to download R, you can go to the R project website. You can download a CSV (comma separated values) version of the cgd R data set. The size of this file is about 19,908 bytes.

Documentation

Chronic Granulotomous Disease data

Description

Data are from a placebo controlled trial of gamma interferon in chronic granulotomous disease (CGD). Contains the data on time to serious infections observed through end of study for each patient.

Details

The cgd0 data set is in the form found in the references, with one line per patient and no recoding of the variables. The cgd data set (this one) has been cast into (start, stop] format with one line per event, and covariates such as center recoded as factors to include meaningful labels.
