I have a need to save gretl sessions with a script

by Fred Engst

Dear gretl team, The reason for my request: For online teaching, I would like to create individualize exam datasets with multiple modeling outputs as icons, and having individualized exam questions stored in the notes page. During the exam, I just send each student their individualized datasets and questions for them to work on. Once they receive the dataset, they just have to open the notes page and see the exam questions stored in there. This is a way to reduce cheating, for each person’s question and dataset are different. I can’t help if someone else is doing the exam for them, but at least they can’t just simply copy from each other. I figured out how to create the random sample datasets, the multiple modeling icons by a script. Saving the exam questions on the notes page is a bit tedious, but doable. I would like to do: Save each session that I created using scrip, but I can’t. It would be great also if I can save text into the notes page using a scrip. Thanks! Fred

Alternative for First Difference GMM

by 3J LEMA

My panel data have these: Number of Companies = 10, Time per Company =9, Number of Independent Variables = 6 I used First Difference GMM with results as follows: *1. Number of instruments =71 while the number of cross-sectional units = 9.* 2. The coefficient of the lag of the DV which is used as an independent variable is less than 1 and statistically significant (p<.001). 3. AR(1) is significant (p<.05) 4. AR(2) is nonsignificant (p>.05) *5. Sargan Test is significant (p<.05)* 6. Wald Test is significant (p<.01). Since #1 and #5 are not OK, then First Difference GMM is inappropriate. I tried the Two-Step Difference and the Systems GMM and all are not OK. Can you suggest an alternative?

Maybe we could have a --tee option to "outfile"; Allin, what do you think? ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------

Re: Storing model output summary

by Cottrell, Allin

You're ignoring the working example I gave you, which is very simple. Just give a filename as the argument to "outfile" (no buffer option) then execute your logit command, do "end outfile", and you'll get a plain text file containing the logit results.

Hi, have you seen the command reference on this?

When you estimaate a model via the console, append -w or --window to the command line, as in logit y const x -w This has the effect of opening a model output window. In that window go to the File menu and choose "Save as...". You get a choice of formats in which to save the output to file (plain text, LaTeX, RTF, CSV). Allin

Storing model output summary

Hi all, I've been trying to look for a way of storing my logit output summary in the console (coefficients, std deviation, p-values). I've only seen $coeff and so on, but I wonder if there's a way to store it all in a txt file without having to rebuild the summary.
