can't read "student_t_table": no such variable
The student_t_table variable is hard-coded somewhere in this function.
You are absolutely right. The use of that particular variable is deprecated (there is no need for such a table anymore). The procedure must be revised. I will look into this.
Fixed in version 0.6.2 (in CVS repository).
Instead of a table for the Student's t distribution use the inverse Toms-322 algorithm.
