It fails, unfortunately:
Error: Script assertion fails in line 32 (undefined):
abs (fisherQ (invFisherQ (i/1000, df1, df2), 1, 100000) - 3/1000) < 1e-11
; 3 1 100000
OK, this may be due to only a minor precision problem in GSL or to
another set of NaN values in GSL, so determining whether a dynamic GSL
library would work for Praat at all will require more testing on our
part. For the time being, and perhaps indefinitely, we'll stay with
statically linking our libraries, at least for all the editions we
produce from here.
Fair enough. It seems that Praat's version of gsl_cdf_fdist_Qinv
(actually the function NUMinvFisherQ defined in dwsys/NUM2.cpp) is
somehow superior to the native function in the GSL library. Have you
already considered contributing your code to the upstream authors of GSL?
All the best,
Rafael
