Output of plot(MackChainLadder(MW2014, est.sigma="Mack"), which=3:6)


  • Updated NAMESPACE file to comply with new R CMD checks in R-3.3.0
  • Removed package dependencies on grDevices and Hmisc
  • Expanded package vignette with new paragraph on importing spreadsheet data, a new section “Paid-Incurred Chain Model” and an added example for a full claims development picture in the “One Year Claims Development Result” section, see also [1] .

Binary versions of the package will appear on the various CRAN mirrors over the next couple of days. Alternatively you can install ChainLadder directly from GitHub using the following R commands:

install.packages(c(“systemfit”, “actuar", "statmod", "tweedie", "devtools"))

Completely new to ChainLadder? Start with the package vignette.
