    panel data - within-group estimate - individual fixed effects retrieved

    Hi TalkStats people! I am analyzing panel data. First, I have to decide whether to use a random or fixed effect estimator. The Hausman test suggests to use the fixed effect estimator (also named within group estimator). Thus, this is what I am using. However, this method eliminates the...

    Hausman test VS Mundlak model; choosing between fixed-effects and random-effects

    I am using panel data and I have to choose between fixed-effect and random-effect models. I run the Hausman test, the H0 (i.e., the difference in the coefficients from the two models is not systematic) is rejected. Thus, I should use the fixed-effect. I also run a second test, which is based...

    matched pairs VS complete randomization - correspondence test housing market

    I work in experimental economics, labor and housing market. I am trying to answer the following question: why do researchers use matched pairs of applications in labor market correspondence tests (typically in hiring context), whereas they use a completely randomized approach in the housing...

    [ self-selection - nonresponse bias] 65% of population answered survey

    Dear TalkStatstters, I want to investigate possible wage gaps between different groups of people with doctorate degree, in my region. So, I have in mind a regression where the dependent variable is the log of the ratio between two average wages. I have administrative data from the whole...

    Fixed effects versus standard errors

    I have experimental data from a correspondence test in the rental housing market. On which ground should I choose between: 1) F.E. for the region where the apt is and cluster s.e. on the day I sent the message 2) cluster s.e. on region and F.E. on day when the message was sent (or...

    test difference in marginal effects for a dummy variable, different computations

    Dear Talk Stats readers, I have a Stata problem. I would like to test whether the difference between the marginal effects of a dummy varaible, obtained first by computing the difference and then by taking the derivative, is statistically significant. I want to implement this test in order...

    change sign estimate manually because of underlying theory

    *****the thread should be: change sign observations variablebecause of underlying theory****** (sorry for the mistakes in the previous version of this post) Dear forum readers, Is someone allowed to put a minus in front of a variable observation, to obtain its contrary, if this is supported by...
