Data sets and R code

SPSS v11 data sets in zipped format, can be imported in R and other programs. Use of the data sets is strictly for educational purposes. If research is considered, please contact me or the primary researchers.

• All.sav: files in one zip file
• Finlayson example: Fmort.sav with mortality in over 1,000,000 surgical procedures, use a weight variable
• Parts of the GUSTO-I data set: West region (n=2188), sample4 (n=785), sample5 (n=429), and sample2 (n=259, March 2014)
• Aneurysm example: aneurysm.sav (n=238)
• Testicular cancer example: t821.sav (n=1094, 821 with LDH measured)
• Outcome of traumatic brain injury: TBI.sav (n=2159)
• Survival data for ch 23: SMART.sav (n=3873)

The package can be installed in R as:
require(devtools)
install_git(“https://github.com/BavoDC/CalibrationCurves”)
It produces nice graphics:
