Hello everybody,
I've seen in "gsl_statistics_double.h" this two functions:
* double gsl_stats_pvariance (const double data1[], const size_t
stride1, const size_t n1, const double data2[], const size_t
stride2, const size_t n2);
* double gsl_stats_ttest (const double data1[], const size_t
stride1, const size_t n1, const double data2[], const size_t
stride2, const size_t n2);
but I cannot see any reference to them in the manual. What are they for?
Thanks and regards :)
A.

Statistical tests (T-test and pooled variance).
There are quite a few undocumented functions in the library. As a
general rule, only the documented functions should be used.
In this case I was planning to move those functions to a separate
directory for other statistical tests.
