... First of all thank you for your answer. I've already read that article and I really liked it. It's very informative and is the article that gave me to understand that there is not only the way of finding DEGs and then run classifier on them but you can just use the whole dataset. The difference now ...

... Hey! You were right. After delete the samples with the small replication number, algorithm run as expected. Also I tried to create and a matrix with the most significant variables from the sparse matrix that returned from the `coef()` function. Take a look and tell your opinion. # Elastic net ...

Comment: C: Multinomial elastic net implementation on microarray dataset , error at lognet a
... So.Once I've found you, let me ask one last thing about weights. Is it reasonable to set weights to your samples if you don't know their difference beforehand ? So in my case, I can not tell if sample A is a bit more important than the sample H and thus I cannot set specific weight values for them. ...

... Thank you very much for the explanation. Very informative and clear. I'm going to try it out. Although I don't understand the following you said : > If you set nfolds to your total number of samples, then you're > essentially doing what's called 'leave-one-out' cross validation If you create ...

Multinomial elastic net implementation on microarray dataset , error at lognet and nfold explanation
... It's my first time trying to implement elastic net algorithm on microarray data and I'm facing some issues. My dataset `DATA` is a data frame that is consisted by 72 observations (rows) and 18703 predictors (columns). Observations are stored as the 18704th column in the data frame and are in replica ...
