Hi, I run into problem when writing a syntax, I don't know syntax that will return true or false if an integer is odd or even.

I am new in R and I want to solve this problem; I have a matrix X (with n-rows and p-colums) my problem is to obtain the products of the vectors of rows and print out only the maximum value and identify the row that gives the maximum value.

...ing my data using discrminant analysis. The problem is that all my dependent variables are categorical which means that the normalty assumption is no longer valid. Can one still use discrminant analysis for such data? Is there non-parametric technique of doing discrminant analysis in R.

...r at cross-road on using discrminant analysis for my set of data. All my dependent variables are all categorical, hence the normalty assumption is no longer valid. Is it still right to use discrminant analysis or is there any non-parametric technique or approach to discriminant analysis?

Hello all, I have a problem of getting the locations of elements in a vector or matrix. I know one can use the command "which.min" or which.max" to get the location of minimum or maximum values in a vector. But is there any command to get the first k minimum values or maximum values in a vector. Thanks --------------------------------- You rock. That's why

Dear, My problems are; 1. Simulate a P-variate multivariate data set (N by P) 2. Draw samples of size n from N (with or without replacement) 3. Obtain eigen values of the variance-covariance matrix of each sample drawn in (2) above. 4. print out the matrix of eigen values as well as the identity of sample generating them. Thanks ---------------------------------

Dear everyone, I am having problem simulating multivariate data. Though I was able to simulate the data, but finding the variance-covariance matrix of simulated data did not give exact covariance matrix used in simulating the data. Unlike some other packages, like stata, using command "corr2data" will simulate data having the covariance matrix exactly with the specified covariance

...f] <- 9 # Fit modified procedure fit<- glmnet(x, y, family="gaussian", alpha=alpha,lambda=lambda1+lambda2, penalty.factor=w4) The question is; Does the code address the modified procedure in as shown in the equation? If not, suggestions are please welcome. Thanks -- OYEYEMI, Gafar Matanmi (Ph.D) Reader Department of Statistics University of Ilorin.
