On this Picostat.com statistics page, you will find information about the Lanza data set which pertains to Prevention of Gastointestinal Damages . The Lanza data set is found in the HSAUR R package. You can load the Lanza data set in R by issuing the following command at the console data("Lanza"). This will load the data into a variable called Lanza. If R says the Lanza data set is not found, you can try installing the package by issuing this command install.packages("HSAUR") 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 Lanza R data set. The size of this file is about 4,195 bytes. |

Prevention of Gastointestinal DamagesDescriptionData from four randomised clinical trials on the prevention of gastointestinal damages by Misoprostol reported by Lanza et al. (1987, 1988a,b, 1989). Usagedata("Lanza")
FormatA data frame with 198 observations on the following 3 variables.
