Dear Octave Help Team,
I am currently trying to analyse mortality data and was wondering whether octave was of use. I have several problems and would appreciate any help with any of the issues I have. The queries I have:
1) I want to fit a model to the mortality data: the model is of the form poly1(x)+exp{poly2(x)}, where poly1 and poly2 are polynomials of required order. The most difficult part of this is that I do not have any starting/initial values.
2) I need to test for model significance; T-test of parameters used, kolomgorov smirnov test, runs test, chi-squared test and any other tests you may think might help.
3) I need to solve any equation: sum from 0 to infinity( Poisson p.d.f)=alpha for each age, a suggested method was the secant method, however the octave code for this is something I have not encountered. Other methods of solving such equations would also be appreciated.
I would truly appreciate any help or advice with these issues.
Many thanks,
Inderpal Kalsi
