Just to add my personal cent to this: I've had similar issues with an R
package some time ago, which kept crashing somewhat unpredictably in the
Solaris tests.
Debugging was hard because it only happened on Solaris, but in the end it
turned out to be due to serious bugs in the code that only h

Your code tests the numbers
1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, …
and correctly prints the odd o
so it
won't auto-print. You have to use an explicit print
print(me.probit(obj))
or use your work-around to convince R that you actually meant to print the
output.
If you dig through the full code of me.probit(), you'll probably find the
function invisible() cal
p at a given starting point; what
you have in mind is to _search_ a string for matches of a regular expression.
Python uses this terminology in its regexp matching functions, and from what
you cited in the documentation so do Perl and PCRE in their docs.

Thanks Ted!
I really appreciate your time!
Thanks for the link about the 'problem of calibration', and your suggestion to
reformulate my model. I had no idea about it before. I certainly learnt
something today.
I will try your suggestions later today and let you know how it works ou

When I take the log(abs(x)) the relationship becomes not satisfactory linear
either.
Any suggestions are highly appreciated!
Thank you!
