Hi there,
I found a (small) bug in the test statistic calculator (performed vie
the GUI):
I did the following test on the variance and after 'OK' an error window
came up:
Error: gnuplot command failed
and the output is:
Null hypothesis: population
variance = 2
Sample size: n = 200
Sample variance = 2
Test statistic: chi-square(199)
= 199 * 2/2 = 199
Two-tailed p-value = *1.027
* (one-tailed = 0.5133)
So, no graph and a p-Value bigger than one.
I'm using the snapshop of gretl with Windows 7.
Best
