Thank you very much, that worked fine

Hi all, I am new in EM so I have following question, if I want to change all values of 0 in an interval variable I have in my dataset to 2, I am having trouble doing that with the replacement node by using the replacement editor, i am not really sure on the options given. Could somebody please guide me? Kind regards and thank you in advance

Thank you very much for the reply

works like a charm, thank you very much for this, date functions are always giving me a hard time

Hi all, I have following column date with this format (datetime) 20JUL16:16:39:12 and i am trying to first get the max date of it per ID and then i want to calculate the difference in weeks between each date and the max date, how can i do that? Thank you in advance

I have tried that but the result is the same, thank you both for your input, i think i will have to do it via commandline Kind regards

chemicalab · ‎05-20-2016

Any good example on doing that?

chemicalab · ‎05-20-2016

OK, how can i do the first option? because when colleagues import the same exact file with the same licensed software they dont encounter this error. Kind regards

Hi all, I encounter this type of error (see attached) when i am trying to import (via menu and import wizard) a txt file into EG. I havent had this problem before so i am kinda stuck. Thank you in advance.

"The same way you can use trees. Of course do not expect the same parsimonious model, that is generated by an algorithm (e.g. UpLift Node in Enterprise Miner ) that creates splits directly maximizing treatment effectiveness" Yes that's exactly what I am after , an upgraded version of the uplift model from 2 to 4 treatments, Thank you

chemicalab · ‎05-05-2015

"I was suggesting simply modelling (and then scoring/calculating) the expected profit. (not probability) This expected profit would be conditional on all the explanatory variables (including the treatment)." What type of algorithm do you suggest for this, any example syntax?

chemicalab · ‎05-05-2015

Then its a simple probability computed,I am looking for a conditional one

chemicalab · ‎05-04-2015

Hi all, I am trying to find a suitable algorithm for a situation similar to uplift models (Y=0/1, Treatment=0/1) but in this case my treatment has 4 levels (1-4) representing different offers and my dependent is a continuous variable for which i am trying to predict the offer that will maximize its expected value. Does anybody have any recommendation what would suit the nature of this problem? Let me know if further clarifications are needed Thank you in advance
