Hi all, This has come up a few times today, so I thought I'd clarify -- Even if you are prevented by your original author from uploading or distributing the data, you should still create a replication file and upload what you can (including the R code that you used). You should also get and report the UNF and cite it in your paper. Here's an example: Gary King; Langche Zeng, 2006, "Replication Data Set for 'When Can History be Our Guide? The Pitfalls of Counterfactual Inference'" hdl:1902.1/DXRXCFAWPK UNF:3:DaYlT6QSX9r0D50ye+tXpA== Murray Research Archive [distributor] I've closely monitoring people's submissions to dataverse, and I don't want to release any replication archives that don't have data files, abstracts, and R code. If you are in a position where you can't upload data, but you have the other components, let me know and I will release your study. Maya

Interpretation of rho for panel-corrected Prais-Winsten regression with FE

by acromanya＠gmail.com

Dear all, I am having trouble interpreting the Rho statistic for a panel-corrected Prais-Winsten statistic with AR1. When fixed effects are introduced in the regression, the rho statistic we are looking at changes from 0.110 to -0.001. Some of the significant coefficients in the regression also change dramatically. Should we be concerned about an rho statistic so close to zero? Is there an optimal rho for this kind of model? Thank you very much! Andrei

dataverse cataloging

by msen＠fas.harvard.edu

Hey folks, Just got some feedback from the Dataverse team that some of you are releasing replication archives without completely cataloging what's going on (e.g., no abstracts, etc.). So, just a friendly request to be comprehensive in your cataloging. It helps the staff and it also helps future scholars find your work down the road. Maya

paper question

by elin＠hbs.edu

Iain, Maya, Wondering how much this paper should be able to "stand alone", vs. require that the reader be familiar with the paper we are replicating. this impacts how much of our paper is going to be taken up with background explaining what the original paper did. For now, we're keeping it short, with just ~ 2 pages on background of the original paper, keeping the bulk about how we evaluated it and augmented it. Does that seem right? Also, is there a general guideline on how long this should be? Thanks!! EXL -- ERIC LIN Technology and Operations Management Harvard Business School Boston, MA 02163 elin at hbs.edu

LaTeX Tables

by federman＠fas.harvard.edu

We have a table in LaTeX that fits on the page, but has a *lot* of columns, which gave us a situation where it looks uncentered on the page, because we have a left margin but the table goes off to the right. It fits but looks weird. Is there any way to either resize or re-center the table so it isn't off kilter like this? Thanks! ~Meryl

RCE environment

by nicolabretscher＠gmail.com

How can I save output when working with R in the RCE environment? It would be useful to save the R workspace, in case I wish to work on the output further on my own computer. Regards, Nicola

amelia Quesions

by yding＠fas.harvard.edu

Hey class, I have two quick questions regarding amelia. Apologies if they have already been answered. First, is the result going to be different if I average my imputed values of the 5 data sets first and then run the models on them? Second, given my results on the 5 data sets, what is the proper way to get the "averaged standard error", do I take the average of the standard errors? Thanks, Iza
