Hi Serge, i need to simplify some code in dhb-numerical and i'd like to know whether i may in the process of doing that move your DhbExponentialDistributionTest to Math-Tests-DHB-Numerical? if you put it in Math-DHB-Numerical in order to refind it simpler, i could put it in a separate protocol tests-statistics in Math-Tests... , would that be ok with you?
btw i looked at the test and i probably dont understand the comment there. i often make inline comments just for myself that are <g> ununderstandable for other users, hence i usually just skip comments i dont understand, im just not sure whether this "testing a random sample seems suspect" is a comment like that. i looked at that test:
"you have:" eg := DhbExponentialDistribution scale: 10. "with mean & stdev" eg average." 10" eg standardDeviation ." 10" "a sample mean follows a normal distribution with a stdev of stdev/(n sqrt) :" 10.0 / 10000 sqrt." 0.1" "you test for an interval of mean 10 +-0.5, hence +-5*stdev" nd:=DhbNormalDistribution new." Normal distribution( 0, 1)" "hence the probability of a test failure is around (well, the book says the error in the [first part of the] calc is smaller than 7.5e-8):" (nd distributionValue: -5)*2. "5.742099990047038e-7"
even if you add twice the possible error this is not really high <g>, but, well ok, what seems suspect? werner
