Hi I have the following formula (I hope it is clear - if no, I can try to do better the next time) h(x, a, b) = integral(0 to pi/2) ( ( integral(D/sin(alpha) to Inf) ( ( f(x, a, b) ) dx ) dalpha ) and I want to do an mle with it. I know how to use mle() and I also know about integrate(). My problem is to give the parameter values a and b to the

Hi, R developers. when running mle inside a loop I found a nasty behavior. From time to time, my model had a degenerate minimum and the loop just crashed. I tracked it down to "vcov <- if (length(coef)) solve(oout$hessian)" line, being the hessian singular. Note that the minimum reached was good, it just did not make sense to calculate the covariance matrix as the inverse of a singular Hessian. In my case i am just interested on the value of the log-likelihood. For my application, I patched it easil...

...te all the way to the bottom of this yet, but the attached code will clearly show the problem. In the version of mle that I've built (which has gotten some ugly bells and whistles added) I added a check which would be more or less equivalent to check if length(start)==0 and then setting oout <- list(par=start, value=f(start), hessian = matrix(numeric(0),0,0) or something along those lines. Or one could change L-BFGS-B to behave the same as the other methods. cheers Ben Bolker --------------------- library(stats4) ## using example from ?mle x <- 0:10...

So I am trying to use the mle command (from stats4 package) to estimate a number of parameters using data but it keeps throwing up this error message: Error in solve.default(oout$hessian) : Lapack routine dgesv: system is exactly singular: U[1,1] = 0 This error sometimes indicates that the list of starting values is too far from optimum but this is unlikely since I picked values close to where the parameters usually end up. I have also tried switching these around a bit....

...to your provider. My question is : "Am I correct in thinking that I can have asterisk answer the incoming call from telco on the PRI, Grab the ANI/DNIS Information and then route it to a channel back via a second PRI Port and have the channel bank pass the ANI/DNIS of the original caller oout to the proprietary box in an analog fashion?" My understanding is that the Proprietary box does its magic and then would need to transfer the call back to a Specific user on the PBX via flash hook transfer. If I am on the right track can anyone point me in direction of channel backs that wil...

Hi, i cant make a three way call using grandstream phones (BT-100) and asterisk using sip, is this supported or i need a zap interface? thanks
