similar to: Elastic net in R (enet package)

Dear R users,? ? ? ? ? ? ? ? ? ? ? ? ? I am using "Glmnet" package in R for applying "elastic net" method. In elastic net, two penalities are applied one is lambda1 for?LASSO and lambda2 for ridge ( zou, 2005) penalty.?How can I? write the code to? pre-chose the? lambda1 for?LASSO and lambda2 for ridge without using cross-validation Thanks in advance? Tayo? [[alternative

Dear R users,   I am new user for elastic net. I am trying to use elasticnet library. I have marker data with 359 markers and 168 samples, and response is metabolites. I am trying to do regression between a metabolite and markers.  But i am getting the following error:   > en<-enet(marker,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE) Error in one %*% x : requires numeric

Hi, List The elastic net package (by Hastie and Zou at Stanford) is used to do regularization and variable selection, it can also do regression. I am wondering if it can perform binary classification (discrete outcome). Anybody having similar experience? Many thanks, -Jack [[alternative HTML version deleted]]

Dear R users, I have problem with extracting coefficients from a object. Here, X (predictor)and Y (response) are two matrix , I am regressing X ( dimensions 10 x 20) on each of columns of Y[,1] (10 x 1) and want to store the coefficient values. I have performed a Elastic Net regression and I want to store the coeffcients in each iteration. I got an error message . I do not

Dear All, I am using "Caret"package for SVM regression and elastic net regression . I can get the final fiited vs observed values. How can I get the coefficients? Any ideas? Thanks Alex [[alternative HTML version deleted]]

Dear Members, I am working on Elastic net and using R package for that. I have two matrix. My response is a matrix of size 50X50 and predictor is also in same size. I want to extract only cloumns from the matrix and do the elastic net analysis then store them as a matrix. library(elasticnet) library(lars) XB<-matrix(rnorm(2500,0,1), ncol=50,nrow=50) y1<-matrix(rnorm(2500,0,1),

Hey gang, I find myself struggling with multiple step definitions in cucumber all the time. I regularly test the contents of my flash[:notice] in steps, since I think that''s part of the behaviour of the app. So, while implementing a new feature, I ran into the following error: /opt/local/lib/ruby/gems/1.8/gems/cucumber-0.1.15/bin/../lib/cucumber/ step_mother.rb:81:in

Hi all, I have recently worked on fts plugin for ElasticSearch. https://github.com/filiphanes/fts-elastic It is forked from fts-elasticsearch as you can see in PR https://github.com/atkinsj/fts-elasticsearch/pull/21 with following changes (maybe some more) - no duplicate json keys in indexed documents, so compatible with ES 7.x - 1 elastic index for all users with routing by username -

Hello, I'm writing to see if anyone here has had any success running Icecast2 (specifically I am using 2.4) on Amazon EC2 behind an Elastic Load Balancer? I have the ELB configured to do TCP loadbalancing rather than HTTP. I am able to connect and to stream music via the ELB, but when I disconnect, the listener count in Icecast does not decrease.

Hello, I got a question about the script function class(SwfdecAsScriptFunction) design in swfdec. Why doesn't a script function mark its target(SwfdecAsScriptFunction::target) in the marking phase? What if the function's target has been destroyed while the function itself is still kept alive? (Answer myself: then there would be a segfault when executing that function) Let me give a

Hi, I have a data.frame containing a Date column. When using write.csv() function to generate a CSV file, I always get the Date column formatted as "YYYY-MM-DD". I would like to have it formatted as "MM/DD/YYYY", but could not find an easy way to do it. Here is the test code: d <- data.frame(ticker=c("IBM", "IBM"), date =

Dear all, I am using modified LARS algorithm (ref: The Adaptive Lasso and Its Oracle Properties, Zou 2006) for adaptive lasso penalized linear regression. 1. w(j) <- |beta_ols(j)|^(-gamma) gamma>0 and j = 1,...,p 2. define x_new(j) <- x(j)*w(j) 3. apply LARS to solve modified lasso problem out.adalasso <- lars(X_new,y,type="lasso") or enet(X_new,

Hi, dears, I am processing some data with 60 columns, and 286,730 rows. Most columns are numerical value, and some columns are categorical value. It turns out that: when ntree sets to the default value (500), it says "can not allocate a vector of 1.1 GB size"; And when I set ntree to be a very small number like 10, it will run for hours. I use the (x,y) rather than the (formula,data).

Hi all; I recently have been used 'maxLik' function for maximizing G2StNV178 function with gradient function gradlik; for receiving this goal, I write the following program; but I have been seen an error  in calling gradient  function; The maxLik function can't enter gradlik function (definition of gradient function); I guess my mistake is in line ******** ,that the vector  ‘h’ is

Dear R users, i would like to transform the following function from R-code to C-code and call it from R in order to speed up the computation because in my other functions this function is called many times. `dgcpois` <- function(z, lambda1, lambda2) { `f1` <- function(alpha, lambda1, lambda2) return(exp(log(lambda1) * (alpha - 1) - lambda2 * lgamma(alpha))) `f2` <-

Hi, I am having problems passing arguments to method="gbm" using the train() function. I would like to train gbm using the laplace distribution or the quantile distribution. here is the code I used and the error: gbm.test <- train(x.enet, y.matrix[,7], method="gbm", distribution=list(name="quantile",alpha=0.5), verbose=FALSE,
