WebCluster robust standard errors (clustered on ID) would be the correct way. Cameron and Trivedi (2009) "Microeconometrics Using Stata" describe this in more detail. To use the Hausman test FE v.s. RE you can substitute RE with OLS. Both RE and OLS rely on the same assumptions for consistency, so if your test rejects RE it will likely reject OLS ... WebMar 19, 2015 · With the –regress- command, Stata performs an OLS regression where the first variable listed is the dependent one and those that follows are regressors or independent variables. Let’s start …

WebOct 27, 2016 · If instead we assume that x is (possible) endegonoues, and use IV regression with z as an instrument, then the asymptotic variance of the IV estimator is: A v a r ( β ^ i v) = σ ^ 2 S S T x ⋅ R x, z 2. Since R 2 is always between 0 and 1, it must be the case that the denominator for the IV estimator is smaller then for OLS (if OLS is ... http://www.econometrics.com/intro/poolols.htm
The topic of heteroskedasticity-consistent (HC) standard errors arises in statistics and econometrics in the context of linear regression and time series analysis. These are also known as heteroskedasticity-robust standard errors (or simply robust standard errors), Eicker–Huber–White standard errors (also Huber–White standard errors or White standard errors), to recognize the contributions of Friedhelm Eicker, Peter J. Huber, and Halbert White.
WebOct 4, 2024 · The lm_robust () function in the estimatr package also allows you to calculate robust standard errors in one step using the se_type argument. See the documentation for all the possible options.
