Dear ALL, I use BEKK package to estimate Bivariate GARCH model. But when the results come out, there's no t-stat or p-value of the estimated coeffients. Does anyone know how to get the significance? Followings are the codes I input, >P1=data.frame(x,y) >y1=mvBEKK.est(P1) >mvBEKK.diag(y1) Anyhelp would b...

Dear All, I attempted to fit a DVEC and a BEKK multivariate GARCH model, but am wondering which package to use. 1. I tried to use "rmgarch" package in R, but I couldn't find the subroutines for DVEC and BEKK. 2. I tried to find "rmgarch" package of R, which is not located on the official R site.

Let''s say you''re using the restful_authentication plugin. You have a model called articles. On the index action of the articlescontroller you simply want to spec out that it''ll scope the results to the ownership of the current_user. It should NOT include any articles other than the articles that user owns. How would you properly spec this out? Thanks for the help!

...afternoon figuring out why "jruby -S rake spec" didn''t generate any output at all (no warnings) on an edge rails app. We were seeing different behaviour on different boxes, and after a while figured out that it was related to a missing diff-lcs gem on one box.

Is it OK to go ahead and generate a Rails 2.0 project with RSpec 1.0.8? Am I likely to run into problems? Would it be best advised to wait or can I go ahead now?

Hi, How can I have a common set of steps that all my stories share? i.e. My stories often start out looking like this: Given a user Joe Given a user Jordan then: Given("a user $username") do |username| @users ||= {} @user_sessions ||= {} @users[username] = create_user(:username => username) @user_sessions[username] = login_as(@users[username]) end I want to share that

Hi , Are there any multivariate GARCH package (e.g., BEKK) in R? I do see a few "projects" constructing multivariate GARCH package, but wonder if there is anyone that is ready for use. Thanks, Miao [[alternative HTML version deleted]]

Sorry to be such a pest but I am trying to learn Ruby, Rails and RSpec all at one go and it is a bit overwhelming. I have previously completed the depot tutorial in the Agile Web Dev with rails book and now I am trying do do it again using RSpec. What I would like to know now is why I am getting a rake failure error at the end of every spec:models run. Is this the expected behaviour when a test

Hi there, I installed the rspec on rails plugin for a new project today and guess what -- it blows up! All by other rspec on rails projects are working fine. I updated all gems & still no joy. Any ideas how I can troubleshoot this one ? Here''s my setup: - ruby 1.8.4 (2005-12-24) [powerpc-darwin8.7.0] - Rails 1.2.5 Installed with svn: ruby script/plugin install

Hi R, I have three queries regarding handling GARCH functions in R. Below I document the same: Unlike S-Plus, R doesn't handle Multivariate GARCH models. R has a package for BEKK GARCH model but not for DVEC GARCH models. The GARCH function in S-PLUS has the capability of fixing some model parameters at certain values to evaluate the fit of a particular model. But the same optionality is not provided by the GARCH models in R. So, how can I overcome these difficulties whic...

Hey all, I am currently working on coming up w/ an easy to use, developer-centric web testing framework to test a J2EE app with. (I have 3 rails apps in production, love rspec, and am currently at a java shop). I''ve looked at selenium, and it just doesn''t seem like it is ready for prime time, and the target audience is developers. So, having said that, does the rspec
