Replacing NaN Values...?
I came up with this not-so-elegant solution: The idea is to find the first and last non-nan indexes and then replace the correspoding nans with them. %vector A=[ NaN NaN NaN 3 6 10 30 100 NaN NaN]; %index of the first non-nan ind1=find(~isnan(A),1,'first'); %index of the last non-nan ind2=find(~... 18 Jun 2010 02:37

is bootci with bootfun returning a vector possible? (at least in newer versions of matlab)
Hi, I am trying to get confident intervals for a vector of coefficients using BCa. I found that bootci can do this work but only if the function handle returns a scalar. I use least squares to find the coefficients from the eq.: @coeff =(y) pinv(H)*y where H is a matrix and y is a vector that need to be bootstraped. ... 18 Jun 2010 01:32

Estimating AR(p)-ARCH(q)
Hey folks, I'm trying to estimate an AR(4)-ARCH(3) model by minimizing the negative of the log-likelihood function. But my "optimal" coefficients explode and are wildly huge. I havn't included the constraint on the coefficients to ensure that the model is stationary as I am not sure how to...I think this mig... 17 Jun 2010 23:22
