Dear R-users,                       I have problem or 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 All my dependent variables are all categorical, hence the normalty assumption is no longer valid.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? Thanks OYEYEMI, Gafar Matanmi Department of Statistics

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 The problem is that all my dependent variables are categorical which means that the normalty assumption is no longer valid.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

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

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.

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

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

Hello all, I have a some scripts on my Linux box, i want to be able to edit it remotely from a browser login into my server at a particular port number, just like Webmin, SWAT etc. eg( http://mylinuxaddy:port). Does any body have idea of how i can acheive this? I would appreciate your response. Thanx --Yemi __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new

Dear all I am a BEGINNER and have R on my Mac. I saved my excel file as .txt file, I have just one column with first row as the column name. My file when read by R looks like this.

Hi. I have Fedora core 1 (kernel 2.4.22) and I downloaded http://developer.osdl.org/dev/iproute2/download/iproute2-2.6.7-ss040608.tar.gz Before upgrading, tc -V shows "iproute2-ss020116", and after shows the same. I had a lot of errors during install (make and make install). Is this lastest version for kernel 2.4? How can I upgrade?? Thanks a lot. Leandro

Hello, Is routing within the same network possible? If it is, what configuration should I put for the firewall/router shown below? I basically want the host debian13 to be able to send packets via a multi-homed firewall. I think the multi-homed firewall involve some routing. +-------------------+ |debian13 | |eth0:192.168.0.13 | +-------------------+ |eth0 |

Don't know if anyone's got experiences on this they'd be able to share... I'm trying to obtain numbers for Kenya/Nigeria, but I'm struggling to find a company selling them. There's one for Nigeria listed on didx.com, but $22/month seems a little steep. Has anyone had any luck getting DIDs for countries in Africa, and are there any companies out there selling them? Thanks

Thank you Zhao for the code. When I replotted the graph after inserting the code in my script, it gave me this error message without plotting the graph: Warning message: In lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : extra argument ?col? will be disregarded.
