By

by Joseph Rickert At a Bay Area R User Group (BARUG) meeting this month hosted by Cisco, Dag Lohmann (the co-founder of Katrisk) gave an electrifying talk on catastrophe modeling for the insurance industry. Catastrophes: cyclones, hurricanes, floods earthquakes, terrorist attacks are rare events (from a statistical point of view) that cause losses and human suffering over large geographic...

## Converting graphs in pdf files to csv format

December 19, 2013
By

Looking at a graph displayed as part of a pdf document is so tantalizing; I want that data as a csv! One way to get the data is to email the author(s) and ask for it. I do this regularly and sometimes get the apologetic reply that the data is confidential. But I can see

## OpenCPU 1.2: Flexible and reliable R function RPC over HTTPS + JSON

In my previous post, I tried to answer the following question Consider  points uniformly distributed on a sphere. What is the probability that the  points lie on a same hemisphere, for some hemisphere (there is no south or north here) ? If I have been able to use Monte Carlo simulations in dimension 2 (on a circle, not on a sphere), I could...

$(Y_1,Y_2)$

This week, I spend some time at the Workshop on Nonparametric Curve Smoothing conference at Concordia. Yesterday afternoon, Noël Veraverbeke show an interesting graph, to illustrate conditional copulas (and the derivation of conditional dependence measures, such as Kendall’s tau, or Spearman’s rho). A long time ago, in my PhD thesis (mainly on conditional copulas) I did try to derive conditional...
