Hi, I'm trying to create number of vectors, part of them are binary and part are continuous. Is there a way in R to generate them with specific correlation between each pair? Thank you in advance. Ariel -- *I like...

Hello, Lets say I have 2 vectors: x1=c("a1"=0,"b3"=2,"e2"=-2); x2=c("c"=3,"d"=4,"f"=5); and vector of names in specific order: N=c("a1","b3","d","e2","c","f") and I...

Hello, Suppose I have one vector of values or even matrix of those vectors and I want to calculate q_k(V/k), where V is the vector, k is a quantile and q_k is empirical k-quantile function...

Hi, I'm trying to create binary variable which distribution conditioned on other variables. That is what I did, x1=rnorm(n,0,1); x2=rnorm(n,0,1); x3=rnorm(n,0,1); if(x1+x2-x3>0.25...

Hello, I have a vector of coefficients from backward selection model that looks like: [,1] (Intercept) -0.15 s1[, 1] 2.65 s1[, 2] 1.81 s1[, 5] 2.35 I'd like to get a new vector that contains...

Hello, I have a data orig.raw that contains 8 predictors and 1 outcome variable. I'm trying to run simulation (bootstrap) and create, let's say, 10 confidence intervals for coefficients estimated by LASSO. I did it with regular...

Hello, I'm trying to use parallel computing in MuMIn package. It worked a couple month ago, but now I'm getting the error. Here is a code: #Data x1 = rnorm(1000) x2 = rnorm(1000) x3 = rnorm(1000) z = 1...

Hello everyone, I have general question about parallel programming. I'm doing simulations that involves bootstrap. For now I'm using parLapply only for bootstrap part and then function "replicate" for simulations. It is very long function, so here is...
