[R] Estimating credit card default probabilities.

Folks, I am working on a credit card defaults and transition probabilities. For example a single credit card account could be in a number of states: up-to-date, 30, 60, 90 days in arrears or in default. * Are there packages in R that do estimation of the transition probabilities given historica

[R] Aggregate data frame across columns

Folks, I have a data frame with columns 200401, 200402, ..., 201207, 201208. These represent years/months. What would be the best way to sum these columns by year? What about by quarter? Thanks for your time, KW -- [[alternative HTML version deleted]] __

Re: [R] Aggregate data frame across columns

Arun, Jeff, Bert, Thanks for your help. I have put a subset of my data below in mySubset. I would like to be able to sum the rows by year. In this case the results would be the result data.frame below. How can I automate something like this and how would I do it quarterly if necessary. The

[R] Creating yyyymm regexp strings on the fly for aggregation.

Folks, This question is somewhat related to a previous posting of mine. I just can't seem to create a generic solution. Here is a function that I found searching around the internet: splitIt <- function(x, n) {split(x, sort(rank(x) %% n))} I use it like so: > splitIt(1:12, 2) $`0` [1] 1 2 3 4

[R] Question about VAR (Vector Autoregression) in differences.

Re: [R] Effect of each term in the accuracy of Nonlinear multivariate regression fitting equation

In this context, "linear model" means linear in the _coefficients_ not (necessarily) linear in the predictors, so your model: JIM ~ z1*A + z2*B + z3*A*B^2 + z4*C*D^3 + z5*A^2*B^2 ... is a linear model (in z1, z2, ...). So you don't need to use nls, lm is probably favourite. You can use all t

It seems so simple to me, that I must be missing something. Subject to Jeff Newmiller's reminder of FAQ 7.31; if the sum is zero then the mean is zero and vice versa. The OP's original attempt of: - l <- 100 aux <- rnorm(l,0,0.5) s <- sum(aux)/l aux2 <- aux-s sum(aux2)

Re: [R] F# vs. R

It's been a long time since I used Fortran, and I have only dabbled in F#, but I do not think translating Fortran (or R) to F# will be easy. F# is basicly a functional language (like ML) and a very differant mind set than Fortran (or R). -EdK Ed Keith e_...@yahoo.com
