Hi There - New to the list, so hopefully I don't mess this up too much ... I am hoping maybe some of you can help me. I have a problem I'm trying to solve regarding customer accounts, attrition and forecasting. Basically, here is what I want to do (not sure of the best way): 1. Track accounts by vintage (i.e., the month of the date of sale). 2. Forecast total accounts at a given time

Hi, I am trying to do some predictive modeling around attrition and want to split the dataset into test and train (80:20) and keep the ratio of attritees:non attrites same. In my dataset the attrition indicator is coded as 0(for non-attritees) and 1 (for attritees) and I want to keep the ratio of 0's to 1 similar. I apologize for this trivial question but this is my second week with R. Thanks, Doy American Express made the following anno...

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

I have a data set with observations on 549 cities spanning an 18 year period. However, some of cities did not report in one or more of the 18 years. I would like to implement the procedure suggested by Wooldridge section 17.1.3 in his "Econometric analysis of cross section and panel data" to correct for attrition. For example the table below indicates that the 3rd and the 7th cities in

Hi there, Command line binaries should only do one thing, and do it well. The job of flac (or flac.exe in windows) is to take something and compress it. Shells implement commands to do things like searches, string matching, looping, and stream editing. I wouldn't want to see Josh waste his time re-implementing and having to maintain "dir", "grep", or "find"

Hi all, I a semi-beginner with R and I am working with the plm package to examine a longitudinal dataset. Each individual in this dataset has a longitudinal weight for the probability that he or she remains in the sample. Unfortunately, I have not found an argument to use weights in the plm function? I tried ?weights=? like in standard lm or in nlme or lm4 but it does not work. I asked the

We are about to abandon GlusterFS as a solution for our object storage needs. I'm hoping to get some feedback to tell me whether we have missed something and are making the wrong decision. We're already a year into this project after evaluating a number of solutions. I'd like not to abandon GlusterFS if we just misunderstand how it works. Our use case is fairly straight forward.

Dear all, First, I would like to thank you for your immense work. My question is about a frequent topic which I am not able to solve - even after hours of search in the mailing lisy. I would like to analyse random-effects (and fixed-effects)models of longitudinal / panel data with sampling weights. I have an unbalanced panel of different individuals in 5 years and income data as well as their

Our CEO, Dr. Dan Steinberg, is planning to visit Europe in May. He would like the opportunity to introduce statisticians (and statistically minded people) to data mining, data mining applications and to forefront data mining tools. Our algorithms are probably familiar to many statisticians (CART, MARS, MART, TreeNet and RandomForests), although it isn't necessary to be a statistician to

Hi, I'm a very fresh newbie to R. My first main question is, what the limitations of R are, what methods can R NOT do, esp. compared to (a) SPSS and (b) SAS? The second question is, how do you handle the data entry, data management and data manipulation in R, to me it seems to be really complicated and confusing?! Are there a kind of "helping tools"? The third question: are
