cv.glmnet
Hi, all: Does anybody know how to avoid the intercept term in cv.glmnet coefficient? When I say "avoid", it does not mean using coef()[-1] to omit the printout of intercept, it means no intercept at all when doing the analysis. Thanks. [[alternative HTML version deleted]]

Jags problem
Hi, all: I met "Non-conforming parameters for function %*%" problem, when I run the Jags model in R. My model is like this: model{ for(i in 1:n){ for(j in 1:t[i]){ et[i,j]<-yt[i,j]-beta0+betax*xt[i,j]+betat*t[i,j] } for(a in 1:t[i]){ for(b in 1:t[i]){ sigma[i,a,b]<-pow(rho0,abs(t[a]-t[b])) } } phi[i]<-

Cannot evaluate subset expression for sigmainverse
Hi, anybody can help me with this? can JAGS solve the inverse of a matrix in the 3-way array? Thank you! for(i in 1:n){ for(a in 1:t[i]){ for(b in 1:t[i]){ sigma[i,a,b]<-pow(rho,t[a]-t[b]) } } sigmainverse[i,,]<-inverse(sigma[i,,]) # this is where jags got error } [[alternative HTML version deleted]]

penalized quantile regression (rq.fit.lasso)
Dear all: I have a question about how to get the optimal estimate of coefficients using the penalized quantile regression (LASSO penalty in quantile regression defined in Koenker 2005). In R, I found both rq(y ~ x, method="lasso",lambda = 30) and rq.fit.lasso(x, y, tau = 0.5, lambda = 1, beta = .9995, eps = 1e-06) can give the estimates. But, I didn't find a way using either of
