Dear list members, Where can I find code for computing the p*p variance-covariance matrix given a vector of p variances (ordered varA, varB, ..., varp) and a vector of all possible correlations (ordered corAB, corAC, ..., corp-1,p)? I know that the covariance between 2 variables is equal to the product of their correlation and their standard deviations: corAB * varA^.5 * varB^.5 and so:

Dear list members, How can I replace the nested for loops at then end of the script below with more efficient code? # Begin script__________________________________________________ # Dichotomous scores for 100 respondents on 3 items with # probabilities of a correct response = .6, .4, and .7, # respectively x1 <- rbinom(100,1,.6) x2 <- rbinom(100,1,.4) x3 <- rbinom(100,1,.7) #

Dear R community I am using the gee package to run logistics regression on paired cases from a panel sample. We are getting request from a reviewer to use sample weights to account for different level of attrition. After searching the documentation I am unable to find a way to incorporate sample weights into the gee formula. I found a way to incorporate precision weight but I understand that I

Hi, In my form I have date field set as ''datetime_select'' which is fine as I wanted it in the same format. But while displaying (list action) it displays date in long format i.e. ''Tue May 30 15:39:00 Central Daylight Time 2006''. How can I format it so that it will just be diaplyed as ''dd/mm/yyyy'' format? Thanks -- Posted via

Here is the situation: I have a ''posts'' table from which ''replies'' and ''articles'' are inherited. Articles have_and_belong_to_many categories, but neither posts nor replies do (it just does

When I try to save a date earlier than 1 Jan 1970, ActionController punts with ActiveRecord::MultiparameterAssignmentErrors.
