All, I need the Ruby equivalent of the Excel PMT function which will calculate a monthly payment amount given an interest rate, a number of months, and a present value of the loan amount. Anyone know where I can find such a beast? If someone can point me to the formula that Excel uses internally, that''s fine too. I know it isn''t very complicated, but I def. don''t

I am trying to use the dmt function in the package {mnormt}. Throughout my algorithm, the covariance matrix is sometime calculated to be singular. When attempting to calculate the dmt function with a covariance that is not positive definite, I would like it to return Inf or NaN instead of an error message. I have been using the try function, however it is not yeilding the desired result. (I did

My goal is capturing the screen as video by taking snaphot bitmaps continuosly (what PushSource eaxmple does) and giving them to the Theora encoder through the DS pipeline (next goal is transmitting this video **).

Hello again, A different but related question to my last one: Does anyone know if one can easily estimate state-space models using ML and the kalman filter using R? I would be especially interested in a relatively flexible function that would allow for estimation of hyperparameters, or could be made to do so. Thanks Michael J.

AJAX & Ruby & Rails newbie here. I''ve got a link to remote that I believe should be working, but doesn''t seem in fact to do *anything*.

I have been working the the pmt function in the {mnormt} package and which requires "S a positive definite matrix representing the scale matrix of the distribution, such that S*df/(df-2) is the variance-covariance matrix when df>2; a vector of length 1 is also allowed (in this case, d=1 is set)" is there a way that I can specify the scale covariance matrix instead? Or
