Hi, I get an error using RcppGSL: fatal error: gsl/gsl_vector.h:No such file or directory. What is the best way to install these files as they seem to be missing?

Hi, A quick bench-mark of an R matrix muliplication 500by500 X 500by10000, all random variates, with matlab reveals a huge difference in speed (5 times at least). Is there anything that can be done in R to speed up the multiplication?

Dear all, I get an error using betrag on this data set :http://dl.dropbox.com/u/1866110/dump.csv. I run it like this regression f2.1=betareg(Y~X1+X2,data=dump) summary(f2.1) I get : Call: betareg(formula = Y ~ X1 + X2, data = dump) Standardized weighted residuals 2: Error in quantile.default(x$residuals) : missing values and NaN's not allowed if 'na.rm' is FALSE In addition:

Anyone know how to esimate parameters in the system: x[k]=Ax[k-1]+ B + Gv[k-1] y[k]=x[k]+Du[k]+Hw[k] a system with exogenous u[k] in the measurement eq., v,w are iid, both eq. are gaussian. Thanks, Oyvind --------------------------------- [[alternative HTML version deleted]]
