similar to: Problem with my analysis

Dear R-helpers                         I am having problem or reservation analyzing 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 The problem is that all my dependent variables are categorical which means that the normalty assumption is no longer valid.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. Thanks  OYEYEMI, Gafar

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 trying to read a csv file using the code; contol <- read.csv("RBS.csv") This is the error message I got; Error in file(file, "r") : unable to open connection In addition: Warning message: In file(file, "r") : cannot open file 'RBS.csv', reason 'No such file or directory' Where was the mistake? -- OYEYEMI, Gafar Matanmi (Ph.D) Senior

Hi everyone. My problem is about multivariate analysis. Given a multivariate data X, of dimension (n by p), n is the number of observations while p is the number of variables. I wanted a sample of size p+1 that will have its product of the eigen values of the covariance matrix to be the minimum among all the possible samples (n combination (p+1)). I have written a syntax with worked well, but the

Dear All The problem is about regularization methods in multiple regression when the independent variables are collinear. A modified regularization method with two tuning parameters l1 and l2 and their product l1*l2 (Lambda 1 and Lambda 2) such that l1 takes care of ridge property and l2 takes care of LASSO property is proposed The proposed method is given

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.

Hi everyone, please I'm having problem importing data from Stata and excel. Help me out. Thanks --------------------------------- [[elided Yahoo spam]] [[alternative HTML version deleted]]

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 ---------------------------------

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 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

OK.. after school ended today, I poked around and found nothing so I started all over again. Followed Louis' instructions at https://github.com/thctlo/samba4/blob/master/full-howto-Ubuntu18.04-samba-AD_DC.txt all the way through but at the end, the resolver is not working - and kinit cannot find a KDC (I'm guessing because the resolver is not working!) This is the only server on the

Hi, why does format(10000, big.mark = "\\,") not give me "10\,000"? How can I get this kind of "big.mark"? Cheers, Marius

I'm already using "doveadm search" to update my squat fts indexes (dovecot.index.search and dovecot.index.search.uids) but I'd like to also update dovecot's thread index file (dovecot.index.thread) using doveadm. I checked the new wiki and the archives but didn't see any option for this. (I'm running 2.0.8) The alternative (AFAIK) is to write a script that signs in
