The release of the R package “googleVis” has made the production of interactive maps through Google’s Chart Tools a simple task. Ignoring the some basic data manipulation the below map...

Just after arriving in Montréal, at the beginning of September, I
discussed statistics of my blog, and said that it might be possible - or
likely - that by new year's Eve, over a million page would have been
viewed on my blog (from Google's count...

Google Earth has become a popular way of disseminating spatial data. KML is the data format required to do this. It is possible to load almost any type of spatial...

In a recent post (here, by @teramonagi), Teramonagi mentioned the use of PCA to model yield curve, i.e. to obtain the three factor, "parallel shift", "twist" and "butterfly". As in Nelson & Siegel, if m is maturity, is the yield of the cu...

As mentioned already here, while we were going to Québec City for the workshop, we had interesting discussions in the car, and Maciej mentioned an article recently published in The Actuary,
Hence, I wanted to discuss (extremely) rare event probabi...

50 days ago (here), I was supposed to be very optimistic about the probability that I could reach a million viewed pages on that blog (over a bit more than two years). Unfortunately, the wind has changed and today, the probability is quite low...

I received recently a comment by FCA (here) who raised an important question, about forecast in dynamic mortality models. (S)he mentioned that from his(her) point of view, the econometric models I considered were "good to predict for the next, say,...

The following simple code can be used to find roots of functions (based on the secant algorithm),
secant=function(fun, x0, x1, tolerence=1e-07, niter=500){for ( i in 1:niter ) { x2 <- x1-fun(x1)*(x1-x0)/(fun(x1)-fun(x0)) if (abs(fun(x2)) < to...

In the previous post (here) discussing forecasts of actuarial quantities, I did not mention much how to forecast the temporal component in the Lee-Carter model. Actually, many things can be done. Consider here some exponential smoothing techniques ...

The final course (since courses end this week in Montréal) can be watched here and there. The drawings from the course can be downloaded here (including last week's). First, to come back on last week's course , we considered
Lee-carter model, i.e....
