Dear R users, I'd like to compute X like below. X_{i,t} = 0.1*t + 2*X_{i,t-1} + W_{i,t} where W_{i,t} are from Uniform(0,2) and X_{i,0} = 1+5*W_{i,0} Of course, I can do this with "for" statement, but I don't think it's good idea because "i" and "t" are too big. So, my question is that Is there any better idea to avoid "for"...

...output, and put it on a webpage or something. I'm to lazy to do it (and besides, I don't have access to TeX, X, or anything else from a text terminal with gcc and vi right now). Hope you like it, Segher -- Suppose we want to calculate a MDCT (encode side): (x_ is input (time) samples, w_ is window, b_ is output (freq) samples): b_k = \sum_{j=0}^{4N-1} x_j w_j \cos{(2k+1)(2j+1-2N) \over 8N} \pi After setting a_j := w_{-j-1+N} x{-j-1+N} + w_{j+N} x{j+N}, j < N a_j := w_{j-1-N} x{j-1-N} - w_{j+3N} x{j+3N}, otherwise (or something similar; the cos'es should agree) we ge...

...lp: My name is Rodrigo and I have a question with nlme package in R to fit a mixed beta regression model. The details of the model are: Suppose that:* *j in {1, ..., J}* *(level 1)* *i in {1, ..., n_j}* *(level 2)* *y_{ij} ~ Beta(mu_{ij} * phi_{ij}; (1 - mu_{ij}) * phi_{ij}) y_{ij} = mu_{ij} + w_{ij} * *with* *logit(mu_{ij}) = Beta_{0i} + Beta_{1i} * x1_{ij} + b2 * x2_{ij} log(phi_{ij}) = Gamma_{0i} + Gamma_{1i} * z1_{ij} + c2 * z2_{ij} * *Beta_{0i} = b_0 + u_{0i} Beta_{1i} = b_1 + u_{1i} Gamma_{0i} = c_0 + v_{0i} Gamma_{1i} = c_1 + v_{1i} * *The vector* *(u_{0i}, u_{1i})'* *has normal...

Hi all, I am trying to minimize the quardratic form w'Aw, with certain constraints. In particular, (1) A=(a_{ij}) is n by n matrix and it is symmetric positive definite, a_{ii}=1 for all i; and 0<a_{ij}<1 for i not equal j. (2) w'1=n; (3) w_{i}>=0 Analytically, for n=2, it is easy to come up with a result. For larger n, it seems difficult to obtain the result. Does any one know whether it is possible to use R to numerically compute it? Thank you so much in advance! Hannah [[alternative HTML version deleted]]

...0,data=train,size=4,linout=FALSE,decay=0.025,maxit=800) It works well and give me ROC 0.85. However, when I want to reproduce the result in java, I cannot get the same prediction as nnet output. I checked modern applied statistics with S and I think the output is as follows: y=sigmoid(a_0+\sum (w_{hk} sigmoid_h(a_h+\sum (w_{ih}*x_i)))) and this is exactly how I reproduce the result, the activation function is logistic function for hidden layer and output layer. I use the exact weights I get from the model. Will anyone be kind of pointing out where thing goes wrong? Thanks Eric -- View...

I have the following time series model for prediction purposes *Loss_t = b1* Loss_(t-1) + b2*GDP_t + b3*W_(t-1)* where W_t is the usual white noise variable. So this is similar to ARMA(1,1) except that it also contains an extra predictor, GDP at time t. I have only 20 observations on each variable except GDP for which I know till 100 values. And most importantly,I have also calculated the coefficien...

Hi, P-values in Durbin-Watson test obtained through the use of functions available in packages "lmtest" and "car" are different. The difference is quite significant. function "dwtest" in "lmtest" is much faster than "burbinwatson" in "car". Actually, you can take a nap while the latter trying to calculated Durbin-Watson test.

On Windows, there exist at least two APIs for dealing with the Registry: The Win32 API (RegCreateKeyA, RegCreateKeyW, etc.) works with null-terminated ASCII or UTF-16 strings. The native API (ZwCreateKey, etc.), on the other hand works with UTF-16 strings that are stored as buffers+length and may contain null characters. Malware authors have been relying on the Win32 API's inability to

I am using 32-bit R 3.1.2 on Windows 7. I recently conducted an `R CMD check --as-cran` on a recently-developed package and received only the 'New submission' note. Research on StackOverflow and on R-devel suggested this could be ignored. I also used devtools::build_win() and received no notes or warnings, other than the one mentioned previously. Lastly, I conducted an `R CMD check` with
