Hi there, I am a new user to R.
Could anyone explain me how to define the quadratic trends for the parameter mu/sigma/shi, when fitting non-stationary GEV distributions? That is the mu/sigma/shi has a quadratic trends as follows: mu(t)=beta0+beta1*t+beta2*t^2 sigma(t)=alpha0+alpha1*t+alpha2*t^2 shi(t)=delta0+delta1*t+delta2*t^2 Thanks Best Regards, Mohammad Ashrafuz Zaman PhD Candidate School of Engineering Building XC, Room 1.02 (Kingswood Campus) University of Western Sydney Locked Bag 1797, Penrith South DC NSW 1797 Australia Tel: 61-2-4736 0398 Mobile: 61-4-30977440 Email: m.za...@uws.edu.au<mailto:muhit.rah...@uws.edu.au> [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
