  • bilby So we have unmasked sionnach as the infamous Jack the Knife? Nov 25, 2009

  • dontcry The song. Nov 25, 2009

  • Prolagus The person or the place? Nov 25, 2009

  • dontcry This is all I know about Indiana: Gary, Indiana, Gary, Indiana, Gary, Indiana... Nov 25, 2009

  • Prolagus dontcry: HA! Nov 25, 2009

  • sionnach "I'm thinking the pools at the Radisson probably are not even deep enough to dive safely. "

    Something tells me that you've never been in beautiful downtown Muncie, dc. All-you-can-eat buffet? Yes! "Swimming pool"? Not a priority in the midwest. :-) Nov 25, 2009

  • dontcry You should not have been diving with all that food in your belly, 'nach. Also, I'm thinking the pools at the Radisson probably are not even deep enough to dive safely. Nov 25, 2009

  • sionnach This brings back hideous memories of a night, back in the dark ages of 1988, spent in the lovely Radisson hotel in downtown Muncie, Indiana, where I discovered an egregious computational error in the presentation I was due to give at the next day's conference, and so ended up having to jackknife the key numerical result - with only a pocket calculator - by hand in my hotel room. As there were 72 observations in the dataset, this involved 72 recalculations of the statistic in question. As I recall, it took me until 4 in the morning, and involved three brandies from the minibar, as well as a club sandwich and french fries delivered from room service at around 2am. The audience was none the wiser, except perhaps for the telltale residue of french fry grease that besmirched a few of the transparencies.

    I learned a valuable lesson about the inadvisability of jackknifing without the appropriate technological tools. Nov 24, 2009

  • Prolagus As a statistical term:

    Jackknifing, which is similar to bootstrapping, is used in statistical inferencing to estimate the bias and standard error in a statistic, when a random sample of observations is used to calculate it. The basic idea behind the jackknife estimator lies in systematically recomputing the statistic estimate leaving out one observation at a time from the sample set. From this new set of "observations" for the statistic an estimate for the bias can be calculated and an estimate for the variance of the statistic.
