Feed: R-bloggers. Author: Anindya Mozumdar. If you search for the phrase “fastest man on earth” in Google, chances are that it will return the answer “Usain Bolt”. It certainly does so for me, even though the results might be different if Google decides to personalize the results for you. This is because currently he holds the world record for being the quickest (9.58s) to run a 100 metres race. Justin Gatlin once did it in 9.45s, but that does not count as the record because he was assisted by the wind. However, as statisticians, we know that a single data ... Read More

Feed: R-bloggers. Author: Jakob Gepp. On my daily commute to STATWORX, I pass the gas station down the street twice a day. Even though I’m riding a bike, I’m still looking at the gas prices. Lately, after a few weeks of observation, I thought to have found some patterns. My statistic sensors were tickling! Of course, I am not the first one to notice patterns. Nearly everyone has their own theory about when to buy cheap gas! Some of the more famous examples are: Everything was better in the old days It’s cheaper in the evening Gas stations at motorways ...

This week I worked for one customer who had emulation of global variables based on temporary tables.Depends on usage, this implementation can be very slow - more due often using temporary tables, a pg_class, pg_attribute tables can bloat, and these functions are slower and slower. So don't use it. There are alternative, much better solution, based on custom configuration variables:Original code: CREATE OR REPLACE FUNCTION public.setvar(_varname text, _value text) RETURNS void LANGUAGE plpgsql 1 AS $function$ 2 begin 3 create temporary table if not exists variables(varname text unique, value text); ...

Feed: R-bloggers. Author: matloff. The prominent conference R/Finance, held annually in Chicago, had a great program yesterday and today. As I wrote following last year’s conference, the organizers were criticized for including no women in its speaker lineup. The problem was that no women had submitted papers for consideration; no input, thus no output. I’m a member of the Editorial Board of the R Journal, and out of curiosity, yesterday I did a gender count among papers I reviewed during my first two years of service, 2017 and 2018. I considered only first-author status, and found that I had accepted ... Read More
