Details:


I have the impression that the tinv-function should be a part of the octave
main core, see:
https://octave.sourceforge.io/octave/function/tinv.html

but typing >> tinv indicates that it belongs to the statistics package. 

When running the regress-function it stops complaining about missing tinv
function, see error message below. Could it be misplaced somehow? 



[B, BINT, R, RINT, STATS] = regress (devpow(bi)', X);
warning: matrix singular to machine precision
warning: called from
    regress at line 117 column 10

error: 'tinv' undefined near line 126, column 126

The 'tinv' function belongs to the statistics package from Octave Forge
but has not yet been implemented.
