    I Autocorrelation Error Interpretation

    Hello, I have a question on Autocorrelation of OLS model. So I encountered a autocorrelation error, and use Cochrane - Orcutt Two-step Procedure(CORC) to fix it. And my OLS became GLS. And I have no idea how to interpret the coefficient on my initial X and Y with the new model. I mean something...

    Prob/Stats Suggestions for a book regarding econometrics

    Hello, I am looking for any online supplemental courses to supplement my book reading of Introductory Econometrics 4e by Jeffrey M.Wooldridge. The book is rather terse and jumps around a lot between ideas presented a couple of pages back and forth. I was hoping if anyone knows a good...

    I Is My Panel Data Sample Size Adequate and Modeling Approach Correct?

    I am using panel- data for 30 countries over 25 years to estimate a regression model. Expenditure on cars is my dependent variable and then I use economic theory to find some explanatory variables. First, is 30 countries and 25 years an ok sample? Or should years > countries? Second, is it an...

    Subforum for quantitative and mathematical economics?

    Here I would like to take the opportunity to suggest the addition of a subforum for the purpose of discussing quantitative and mathematical economics. This idea came up after I posted in a few recent topics (1st topic, 2nd topic). I am also partially motivated by QuantEcon, a website pointed out...

    What sparked Justin's renewed interest in physics and math?

    Hi all, I have recently become interested in physics and maths again - I have a strong background in statistics (econometrics) from Uni a long time ago, and always have enjoyed maths and physics, but mostly just for fun. I hope to learn here, and maybe contribute something worthwhile. Thanks...

    Your thoughts on taking 3 math classes and Econometrics?

    So I in a couple more months I will be completing my Gen. ed. requirements(which I'm so happy about!), but now I am wondering if I should fill all my available time slots with all science and math courses. This coming semester I will be taking Intro to Probability Theory, Numerical Analysis, and...

    Multiple regression analysis, econometrics, and statistics

    I am sooo lost in this class, please help. 1. Let the true (population) model be y = B0+B1x1+B2x2+u where u is an unobserved error term with u (conditional) x1, x2 and N(0, sigma^2). Hence, u is normally distributed with mean 0 and variance sigma^2 (i.e., E[u (conditional) x1, x2] = 0 and V...

    Is the con gone from Econometrics?

    Is the "con" gone from Econometrics? (spillover from the thread on the Easterly piece) Ed Leamer wrote a famous piece in the early 80s decrying the ad hoc BS nature of most econometric research entitled "Lets take the Con out of Econometrics" Focusing on the poorly constructed and...

    Programs What Do You Think? Stats vs Econometrics

    Well what are your opinions? Would not having a solid grounding in statistics be more useful than a solid knowledge of the applications of econometrics?

    Book recommendation for Econometrics class

    I need some help for my grad Econometrics class. The book we are using (Woolridge, Introductory Econometrics), doesn't go quite as deep into the math as the lecture does. As a result, it is difficult for me to follow what's going on, even if I read ahead. If anyone could recommend a text that...

    Econometrics: Controls and Difference-in-Differences

    Sorry for the double post with the SS section -- I thought this was probably a better place to ask this question. Hello all, I'm working on an econometrics project in which I'm using difference-in-differences approach to estimate the effects of the 1996 TANF welfare reform in the US. My main...
