| Sep 16, 2022 at 20:24 | comment | added | whuber♦ | It would be fair to characterize this rule as numerology. One byproduct of following it would be that you almost always obtain p-values (and other proportions) that can be expanded to arbitrary precision, usually without any visual evidence of repetition, suggesting to the unwary that you have achieved far greater precision in your results than permitted by the number of replications. | |
| Sep 16, 2022 at 19:03 | comment | added | Henry | @Tim - I had assumed (possibly wrongly) that $1000$ was the number of replications rather than the samples size with replacement | |
| Sep 16, 2022 at 19:00 | comment | added | Henry | If you use $1000$ and your statistic is always an integer, then a bootstrap average will have no more than three decimal places. I see nothing wrong with that. Perhaps the risk is that it will end $\ldots50000$ raising a rounding question (though this is an argument against using any even number) | |

| Sep 16, 2022 at 16:41 | comment | added | Dikran Marsupial | I personally prefer using integer powers of two - being a computer scientist, they are what I consider to be "round numbers". More seriously, halving and doubling seem to be less of a blunt instrument than multiplying and dividing by ten. 5 or 10 seems to be an anthropocentric decimal number perspective. As they will be implemented by a digital computer using binary representations, I would be mildly surprising if there was a good reason for this (but you live and learn ;o). Some "simple" decimals don't have finite binary representations so what is simply to us may not be for the computer. | |
