Hi, all! I would love if someone could help me figure this out. I can''t seem to see why the following fails: Here''s the spec: it "should redirect back to the index page" do Coupon.should_receive (:new).with({"name"=>@expectedName,"amount"=>@expectedAmount}).and_return(@coupon) @coupon.should_receive(:save) response.should

Hello World! I'm working on my thesis right now (something about financial immunization) I'm currently working in the basics, doing a matrix that lists the present value (or weight) of every combination of coupon rate and term to maturity, this is the code I have right now which is giving me a "longer object length is not a multiple of shorter object length" #start

All, I''m missing something simple, I think. I am writing a spec to say that my CouponController should create a new coupon from the form parameters, then set the current user.

I am a bit confused about counter_cache here. The API docs http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html say that only the belongs_to association can take the :counter_cache option. When I try to use it on a has_many I get an "unknown key(s): counter_cache" error. Why would this be the case? belongs_to means that this model has a field with an id

I wanted to submit a patch for this, but I''m unsure where the specs would be to update. I found the necessary mapping in rspec_autotest.rb, but I can''t find any specs anywhere. Help? I just need to have /app/views/coupon/index.html.erb to map to

Dear R helpers   I am calculating the 'Yield to Maturity' for the Bond with following characteristics.   Its a $1000 face value, 3 year bond with 10% annual coupon and is priced at 101. The yield to maturity can be calculated after solving the equation -   1010 = [100 / (1+ytm)]  + [100 / (1+ytm)^2] + [ 1100 / (1 + ytm)^3]   This can be solved by trial and error method s.t. ytm = 9.601%.

Hi guys I have data that contains the variances vt of the yields of 1, 2, 3, 4, 5,10, 20 year bonds. Assuming the Hull-White model for the yield of a t-year zero-coupon bond, I have to estimate the ? of the Hull-White model using nonlinear least squares and give a 95% con?dence interval for each parameter. Please can you guys tell how to find out ? using R. Any suggestion regarding what functions
