Is there a way to estimate a nominal response model? To be more specific let's say I want to calibrate: \pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m e^{\xi_{h}+\lambda_{h}\theta_j}} Where $\theta_j$ is a the dependent variable and I need to estimate $\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$. Thank you, Mauricio Romero Quantil S.A.S. Cel: 3112231150

Hi, I am trying to create Bid/Ask for each second from a high volume stock and the only way I have been able to solve this is using loops to create the target matrix from the source tick data matrix. Looping is too slow and not practical to use on multiple stocks. For example: Bids Matrix (a real one is 400,000++ length): Bid Time 10.03 11:05:03.124 10.04 11:05:03.348 10.05

I've installed steam and it runs (extremely slow though), but when I log in and open the my games tab none of my games are shown. I know the games are still registered to my account though because when i use my old windows computer they are still all there. Also when I tried to repurchase one of my games I was told that the software i wanted to purchase wasn't available in my location yet

My son is taking some programming courses in school and it would be very helpful if he could run Visual Studio on his Mac. I own older VB5 and Visual Studio 6 (from my old PC days). [Embarassed] I cannot figure out how to install Wine on his Mac. Can someone please guide me (e.g. show me all the steps I need to follow to install Wine) so that I can then install VB5 and VS6? He's not

ok i've waited a day with steam running and i've stoped and started steam many times and my games still don't show up in the "my games" tab. The same message still appears when i try to repurchase my games saying that the software i want to purchase is not offered in my area. could it be that steam is misreporting my location the the servers? im using ubuntu 8.04 and wine

Dave, on another topic, might I recommend that you and DHH publish an updated version of the Agile guide right away when 1.1 comes out? You could reuse much of your material and it would do a lot of good to help make sure there is still a good centralized source of reference for Rails. Without that book, there really is not a good one-stop source of information for people to learn how to use

What you and so may others on this lise seem to forget is that Cisco is a company offering bsuiness products for businesses. Businesses typically pay by check and wire transfer, especially for items such as this. If you want home-user pay-by-credit-card service, buy products from Belkin's home line and similar. Oh...what's that? None of these cheesy Stocked-at-Costco hardware
