Hi, Bob Muenchen's book is now out on release. Its terrific for a step by step tutorial for doing stuff in R, even if all you know is SAS and SPSS. Check this out here http://rforsasandspssusers.com/ and at http://www.amazon.com/SAS-SPSS-Users-Statistics-Computing/dp/0387094172/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1217456813&sr=8-1 Regards, Ajay www.decisionstats.com

Hi List, I had the pleasure of taking Dr Bob Muenchen's interview for his upcoming book R For SAS and SPSS users. He has spent 27 years in this field while I have spent almost that much on earth. So this is more like a fan blog interview. I thought it would be of use to people curious about R, or even SAS , or SPSS if they have not worked on either of these packages before. Having fought my

R and its GUI Rattle helped me establish a data mining consulting startup on my own, without taking bank credit . People I met on the forum and especially books like rforsasandspssusers.com/ <http://rforsasandspssusers.com/> helped me ease the transition to the new Object Oriented method from the earlier - even a monkey can create shakespeare if he types enough kind of analytics software.

Hi everyone, I'm working on a multi-level model based on one of the "radon" example from Gelman & Hill's book ( http://www.amazon.com/Analysis-Regression-Multilevel-Hierarchical-Models/dp/052168689X/ref=pd_bbs_1?ie=UTF8&s=books&qid=1237069199&sr=8-1 ). I add an "region" indicator (has numeric values from 1 to 5) as the varying intercept in my model (I

Hi All, I have substantially expanded the table that compares SAS and SPSS add-on modules to somewhat equivalent R packages. This new version is at: http://r4stats.com/add-on-modules and I would very much appreciate any feedback you might have on it. The site http://r4stats.com is the replacement to http://RforSASandSPSSusers.com and includes the support files for both "R for SAS and SPSS

All I have been looking into the books on performing statistics in R, in particular I am interested in General Linear Mixed Models, for Randomized Complete Block Design Experiments The list I have come away with so far is: Mixed Effects Models in S and S-plus by Pinheiro (2002)

I want to specify a 2-level mixed model using the lme function in order to test an a priori hypothesis about the between-group values of the slopes but don't know how to do this . Here is the problem. Consider first the case of a single group. The model is: Y_i= a +bX_i + error where I indexes the different values of X and Y in this group . The a priori hypothesis of the slope is: b=K.

Dear Lists, Here are my latest posts on retrenching and locating facilities better. Do you have anything in academic papers that use data mining- analytics for 1) Better Employee ROI quantitative measurement or cutting costs rationally based on data rather across the board. 2) Locating facilities based on pure quant based approaches than local supply demand conditions. Specific application for

Often it is useful to keep a "codebook" to document the contents of a dataset. (By "dataset" I mean a rectangular structure such as a dataframe.) The codebook has as many rows as the dataset has columns (variables, fields). The columns (fields) of the codebook may include: ? variable name ? type (character, factor, integer, etc) ? variable label

There is a code from SPSS Syntax do if sub(ATVK,2,2)="01". comp strata=1. else if sub(ATVK,2,2)>="05" and sub(ATVK,2,2)<="27". comp strata=3. else if sub(ATVK,4,2)>"20" or sub(ATVK,6,2)>"20". comp strata=4. else if sub(ATVK,4,2)>"00". comp strata=2. end if. value labels strata 1 "R 2 "Li" 3 "M" 4

Dear R-helpers, I know of two ways to reading data within an R program, using textConnection and stdin (demo program below). I've Googled about and looked in several books for comparisons of the two approaches but haven't found anything. Are there any particular advantages or disadvantages to these two approaches? If you were teaching R beginners, which would you present? Thanks, Bob

Dear List, Please find an interview from Michael Zeller ,CEO, Zementis. Mike talks about how to use an existing model ( created in R) , using PMML as an intermediate for exporting the model, and deploying it on a cloud computer for as low as 1 $ per hour. Regards, Ajay *Ajay-* *What are the traditional rivals to scoring solutions offered by you. How does ADAPA compare to each of them. Case

Dear Lists, This is an off topic (OT ). I recently took Anne Milley's interview .In Part 1 of the interview , Anne talks about SAS, WPS, other softwares she studied like SPSS,.She also talks about the difference between small and big companies , what sets SAS apart and the famous licensing model of SAS Interview – Anne Milley, SAS Part 1<http://smartdatacollective.com/Home/16909>

Dear R users, I am working on the Value at Risk (VaR) for the Operational risk. For a given loss data, we try to fit some statistical distributions using Kolmogorov-Smirnov (KS) test and A-D test and then for fitted distribution using the estimated parameters, the losses are simulated and the VaR is arrived at. The typical problem faced by the banks is the paucity of Internal loss data and thus

I am attempting to fit a partial credit model using the PCM() function in eRm. My data set comprises 88 items in 43 individuals with possible scores 0,1,2,3. Attempting either a PCM or RSM model fit simply hangs - no error messages but no return to command prompt and a continuously spinning "work in progress" indicator. The scores are from an instrument whose relevant psychometrics

No I am not on the payroll for these people. or any relation of any kind ;) I just like cloud computing thats all Appreciate your kind consideration Mr Simpson- I was not sure of the list so mailed all 3- .
