Hi, I am using gsl_fit_linear to fit a straight line through my data samples. Incidentally, I came across a situation when the data samples lie on a vertical line. I observed that in this case gsl_fit_linear returns everything as (nan). Is it a known behavior or there may be something wrong at my end?
I passed the following data samples to this function:
{(50, 52), (50, 50), (50, 53), (50, 49), (50, 51)}
Please help.
Regards,
Ruchin.
