"Readers' Forum" Page

I've added a new page to this blog - it's titled "Readers' Forum". You'll see the tab for it in the bar just above the top post on the page you're reading now.

Some explanation is in order.

What?
The Readers' Forum is intended to be a "clearing house" for questions and requests relating to econometrics'

As I say in the preamble to the new page,
"Please feel free to use the "Comment" facility below to provide questions and answers relating to Econometrics. I won't be able to answer all questions myself, but other readers may be able to help. The Forum will be "lightly moderated" to avoid spam and inappropriate content."
Please note the italicized passage above.

Why?
Every day, readers post (or attempt to post) lots of "comments" on the various posts on this blog. In many cases, these are not comments at all - they're questions, requests for assistance, and the like.

All comments are moderated - I get to give them the "O.K." before they actually appear. That's just fine for genuine comments. Unless they're spam or contain inappropriate content, I invariably "approve" them right away.

However, in the case of questions and requests I prefer to delay approval and post a response simultaneously. Regrettably, this has meant that, increasingly, there is often a delay in getting this out there. 

Sometimes, the requests are, quite frankly, unreasonable.I won't go into the details here, but let's just say that there's a difference between a blog and a free consulting service.

I also try to be very careful when it's clear that the request comes form a student. I certainly don't want to get into a situation where I'm "getting between" that student and their instructor/supervisor.

In short, I like to try and be helpful, but I can't keep up with the demand. I do have a job!

Hopefully, the new forum will free up some time for me to focus on substantive posts, while still providing an opportunity for discussion.

  1. For econometric and statistical questions, there is a great resource called "Cross Validated". From the site itself: this is "a question and answer site for people interested in statistics <....> built and run <...> as part of the Stack Exchange network of Q&A sites". It functions well and often provides timely and good quality answers for a wide variety of questions. For someone stuck with a concrete problem in econometrics, I know no better place to turn to.

  2. Hello! i am studying the impact of trade openness on manufacturing growth from 1967 to 2013 in Tunisia. my variables are Manufacturing value added(MVA), openness(OPEN), GFCF and manufacturing labor force (MLAB)
    1/ MVA (lag1) and MLAB (lag4) are I (0) no constant , no trend
    MVA, OPEN and GFCF are stationary at first difference and satisfy the 3 equations of ADF test but MLAB at first difference is only stationary when I include constant and trend. can I claim that MLAB is stationary at first difference (i mean is not I (2)) ??can I run ARDL model in this case?
    2/I include trend and intercept in my ARDL model but their coefficients are not significant, what should I do? can delete them and estimate again my model? in this case what critical value I should consider for my ARDL model? unrestricted intercept and unrestricted trend //or no intercept and no trend because their coefficient are not significant..what best software I can use?
