GARCH(1,1) MLE Question
Hi all just some questions: We have a process: y(t) = c + d*y(t-1) + e(t), h(t) = w+a*e(t)^2 + b*h(t)^2, We got the log-likelihood function with is: sum(-0.5*ln(2pi)) -sum(0.5*ln(h(t)^2))-sum(0.5*e(t)^2/h(t)^2)) where e(t) = y(t)-c-d*y(t-1) How do we estimate the coefficients c,d,w,a,b? Is it that we fir... 26 Apr 2010 09:08

surface plot colorbar font size changes
Hello there, I want to create some surface plots and include them in my LaTeX document. Therefor I changed the font size of the colorbar with the property editor to 15 pt.

Partial derivative
I would like to ask how to calculate in matlab second partial derivatives d^2f/dx^2 , d^2f/dy^2 , d^2f/dxdy , when f is function of x and y. Then f , x and y are given by 2D matrix of discrete values, derivatives should be the same representation. I was trying to use diff and gradient, but both give me different result... 26 Apr 2010 08:02

importdata issues
Hi, I export data from a secondary program into a text file with data = importdata(InData, ' ', 16); I have written a script which processes this data and it has always worked fine. I get: data (11x 421 double) textdata (16 x 421 cell) colheaders (1 x 421 cell) However, I have added another couple of c... 26 Apr 2010 08:02
