I am looking for an elegant solution to the following problem. I have one that works, but it is ugly. In a questionnaire, each of 80 subjects answered 8 questions about each of 30 different behaviors. My main method of analysis is within-subject regression, in which I predict the answer to one of the 8 questions from answers to some of the other questions - different subsets for different

...o make a direct method age-adjustment to some complex survey data. I have played with postStratify, calibrate, rake, and simply multiplying the base weights by the correct proportions - nothing seems to hit the published numbers on the nose. I am trying to replicate any of the following: the stdize and stdweight parameters from a Stata complex survey analysis command (like this) svyset [w= WEIGHTVAR], psu(PSUVAR) strata(STRATAVAR) vce(linearized) svy: mean VARNAME, stdize(agecat) stdweight(agewt) the stdvar and stdwgt parameters from a SUDAAN proc descript call the...

Hi, I need to compare two matrices with each other. If you can get one of them out of the other one by resorting the rows and/or the columns, then both of them are equal, otherwise they're not. A matrix could look like this: [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [1,] 0 1 1 1 0 1 1 0 [2,] 1 1 0 0 0 1 0 1 [3,] 1 0 1 0 0

...icative scatter correction (msc) implementation - Functions for plotting predictions, validation statistics, coefficients, scores, loadings, biplots and correlation loadings. The main changes since 1.0-3 are - mvr, mvrCv and predict.mvr now has builtin support for scaling of X. - A new function stdize for explicit centering and/or scaling. - Correlation loadings plot (corrplot). - New argument `varnames' in coefplot, to label the x tick marks with the variable names. - loadingplot, coefplot and plot.mvrVal can now display legends, with the argument 'legendpos'.

SAS Enterprise Miner recommendeds to standardize using X / STDEV(X) versus [X ? mean(X)] / STDEV(X) Any thoughts on this? Pros Cons Philip
