• Code:

R code for Cumulative Burden (Mean Cumulative Count) estimation: This version of code illustrated the difference between "sum of CumIs" and "MCC" that was discussed in the 7th and 8th paragraphs in the manuscript.

R code for Cumulative Burden estimation through "sum of CumIs" with 95% confidence interval: This version of code calculated MCC through"sum of CumIs", with the option to get 95% confidence intervals through bootstrap.

Example datasets used in the above code: "dat for MCC14.csv"     "smndata.csv"    "crprep_Revised.R"
