* ministat: disallow negative variance / nan StddevEd Maste2018-02-211-0/+6
| | | | | | | | | | | | | | | | | With all values identical it was possible for Var() to return a negative value due to limited floating point precision, resulting in "nan" reported as Stddev. Variance cannot actually be negative, so just return 0. We can later investigate alternate algorithms for calculating variance to reduce the effect of catastrophic cancellation here.

* Reduce the bogosity of ministat's % difference calculations.Colin Percival2016-11-051-1/+7
| | | | | | | | | | | | | | | | | | | | | | The previous calculation used an approximation which was only valid in cases where the means being compared were similar; this resulted in very odd claims being made, e.g. that 0 +/- 0 is a difference of -100% +/- 1% from 100 +/- 1. The new calculation scales sample standard deviations by the means, and yields approximately correct percentage difference bounds providing that the reference population is bounded away from zero. (In the case where the values being compared are not sufficiently bounded away from zero, the distribution of ratios becomes much harder to calculate, and is not likely to be useful anyway.) Note that when ministat is used for its intended purpose of determining whether two samples are statistically different, this change is unlikely to have any noticeable effect; in such cases the means will be similar enough that the correction applied here will be minimal.

This is not entirely correct. The mini-help is more accurate: '-w : width of graph/test output (default 74 or terminal width)' In other words: the man page fails to explain that ministat will default to the terminal width, not 74. It will only fall back to 74 if stdout is not a TTY. Submitted by: Ben Hutchings <ben@decadent.org.uk> Approved by: philip (mentor) Notes: svn path=/head/; revision=280701
