I'm a property-casualty actuary, use R in at my job, and lurk on the list. In conjunction with one of its meetings, the Casualty Actuarial Society (I'm a member) is looking for proposals from people to teach a workshop in R and I thought members of the list might be interested. I've pasted the information below. My apologies if this posting violates list rules. Thanks. Kevin http://www.casact.org/cms/index.cfm?fa=...

...would like to use the method of Pepe et al Stat Med 1991; 413-421 - essentially the prevalence is the Kaplan-Meier prob[having the condition at time t] - KM prob[recovery by time t] (also divided by 1-KM[death by t], although death is not an issue with this data). I can easily produce the relevant actuarial data for either the condition or recovery using survfit(eg survfit_cond$time , survfit_cond$surv, survfit_rec$time, survfit_rec$surv). I then have to calculate (survfit_cond$surv-survfit_rec$surv) at each event time point. Can anyone help me with an easy method to implement this? Or suggest an ea...

Has anybody written an actuarial (life) survival procedure, this does not appear to be an option in the survival package? This approach is common in orthopaedic surgery to demonstrate the survival of prostheses. I need to apply the "modified" lower conf.int because of the censoring over time. I want a life table whi...

...can see that in the second regression, i.e. R2~-1+p1+R1, the coefficient for p1 is not significant. I wonder if I can run this bivariate regression again with the constraint that the coefficient for p1 in the second regression equation is zero? Thanks a lot.

Hi R users: I will like to know if somebody works on insurance statistics (actuarial problems) and had use TRICAST, and can tell me if with all the R tools it can be build a solution like TRICAST or similar. In a word: Do you think that R has all the statistical tools (I mean modeling tools) to make a job similar to TRICAST? Does TRICAST has modeling tools that are not impleme...

...ontinuous distribution ranging from 0 to infinity, I want to sample from a percent damage distribution from 0-100%. One obvious solution is to use runif(n, min=0, max=1), but this does not seem to be a good idea, since I would not expect damage to be uniform. I have not seen such a distribution in actuarial applications, and rather than inventing one from scratch I thought I'd ask you if you know one, maybe from other disciplines, readily available in R. Thank you in advance. ----- ~~~~~~~~~~~~~~~~~~~~~~~~~~ Diego Mazzeo Actuarial Science Student Facultad de Ciencias Econ?micas Universidad de...

Greetings, Version 0.1.4-0 of the ChainLadder package is available via CRAN and http://code.google.com/p/chainladder/ The ChainLadder package, which is focused on claims reserving methods typically carried out by property/casualty insurance actuaries, has recently been enhanced to implement the methods in David Clark's 2003 CAS (Casualty Actuarial Society) *Forum* paper "LDF Curve-Fitting and Stochastic Reserving: A Maximum Likelihood Approach." Clark's methods are ready to be put to use on a wide variety of "triangles&...
