$the Grumble distribution and an ODE$

As ‘Og’s readers may have noticed, I paid some recent visits to Cross Validated (although I find this too addictive to be sustainable on a long term basis!, and as already reported a few years ago frustrating at several levels from questions asked without any preliminary personal effort, to a lack of background material to

## Confidence vs. Credibility Intervals

$\theta$

Tomorrow, for the final lecture of the Mathematical Statistics course, I will try to illustrate - using Monte Carlo simulations - the difference between classical statistics, and the Bayesien approach. The (simple) way I see it is the following, for frequentists, a probability is a measure of the the frequency of repeated events, so the interpretation is that parameters are...

## Flowers/Fractals

November 21, 2014
By

Last week, I attended a "Flower Fest" where I had the opportunity to admire several of the most beautiful and awarded flowers, orchids, and decoration plants. Surprisingly, though, I never had thought of flowers like fractals the way I did this time. Fractals attract lots of interest, especially from mathematicians who actually spend some time … Read More...

## Reinterpreting Lee-Carter Mortality Model

November 18, 2014
By

Last week, while I was giving my crash course on R for insurance, we’ve been discussing possible extensions of Lee & Carter (1992) model. If we look at the seminal paper, the model is defined as follows Hence, it means that This would be a (non)linear model on the logarithm of the mortality rate. A non-equivalent, but alternative expression...

Using Markdown and Pandoc for PublicationThe other day I was involved in editing job, in which I was supposed to edit 18 articles written in Microsoft Word (doc/docx format) and convert them into pdf format (for printing into a book) and html format (for web publishing). Manuscripts written by people not proficient in doc(x) format are notorious...

## Shapefiles from Isodensity Curves

November 3, 2014
By

Recently, with @3wen, we wanted to play with isodensity curves. The problem is that it is difficult to get – numerically – the equation of the contour (even if we can easily plot it). Consider the following surface (just for fun, in order to illustrate the idea) > f=function(x,y) x*y+(1-x)*(1-y) > u=v=seq(0,1,length=21) > v=seq(0,1,length=11) > f=outer(u,v,f) > persp(u,v,f,theta=angle,phi=10,box=TRUE, +...
