Re: drop data that is stored in the r2mlwin object?

Thanks, Chris, for the input. Your for-loop works fine. Just for the sake of details, how would you write a function that removes the data, chains, etc and only keeps the absolute minimum to show the results with the print function? Experimented a bit, but I am still left with a rather large object....

Re: drop data that is stored in the r2mlwin object?

Thanks, Chris. Two follow-up questions: 1) removing the data reduced the object size by ~15 %. Could you advice about what else I could remove to save space? Checked through the s4 object but it is difficult to know what one can through away if one only wants to keep the model output. 2) If I want t...

drop data that is stored in the r2mlwin object?

Hi

I wonder if it is possible to drop the data that is stored in the r2mlwin object? As I am estimating many models, these objects get very large (~4gb each), and start eating my ram very quickly.

Thanks in advance

looping through a list of independent variables

Hi Has anyone figured out how to loop/iterate through a list of independent variables (and dependent variables)? Preferably with the doParrallel package, as Chris suggested here https://www.cmm.bristol.ac.uk/forum/viewtopic.php?f=7&t=1213&sid=303ac6cf55c2133ea2bcd243d352de0c Suppose I want to iterat...

Re: model.matrix() and terms() for R2mlwin objects

(A) Thanks, Chris. Good idea, re bypassing the VGAM package entirely. It does not seem that predict() is sensitive about having variables in the data passed to it, that are not used in the model. Right? (B) Another issue. I replicated the module in both lme4 and R2mlwin, but I am getting quite diffe...

Re: Relative risk ratios in R2MLwiN

Thanks for the clarification, George.

Sounds that the language that STATA is using is a bit confusing/misleading compared to what the statistics community tend to use.

Nevertheless, is it possible to obtain relative risk from an ordinary logistic regression from Mlwin?

Best,
Adel
