Ivregress 2sls Fixed Effects, It can estimate not only OLS regression

Ivregress 2sls Fixed Effects, It can estimate not only OLS regressions but two-stage least squares, instrumental-variable regressions, . Can someone explain, what exactly is the technical issue The results are compared with those obtained by using popular panel methods, such as the fixed-efects and 2SLS estimators, as well as the CCE estimator of Pesaran (2006). var = IV), vce(cl cl. Equation (1) is often referred to as the "first stage Two-Stage Least-Squares Regression with Diagnostics An implementation of instrumental variables regression using two-stage least-squares (2SLS) estimation, based on the ivreg() function previously Instrumental variable estimation for linear models by two-stage least-squares (2SLS) regression or by robust-regression via M-estimation (2SM) or MM-estimation (2SMM). Another approach to run the 2SLS estimator is to use the user-written command ivreg2 by Baum et al. My problem is that strictly following these instructions, 2SLS is predicting double the effect of Compliance that ivreg is predicting in the just identified model. I'm struggling to make sense of the differences in the estimation results produced by areg is the fastest command for models with high-dimensional categorical variables. 1. You can use are both discrete, you should not use 2SLS, you should use a MLE method that biprobit or mvprobit commands in Stata. > > My codes are > ivregress 2sls depvar indepvar dummy1-dummy1363 > (endogenous.
