When the measurement error variance in absolute or relative (reliability) form is known, adjustment is simple. We link the (known) estimators for these cases to GMM theory and provide simple derivations of their standard errors. Our focus is on the test statistics. We show monotonic relations ...

I was recently trying to do just a very simple linear regression on x vs. y -- I got this error message: IndexError: tuple index out of range I wasted 3 minutes trying to figure out if my x and y vectors didn't have the same lengths (the...

This chapter discusses the usefulness of instruments to account for measurement error in the case of linear, nonlinear, and nonparametric regression models. This chapter additionally discusses how to use instruments in empirical work when the assumption of classical measurement error is violated (JEL: ...
Simple linear regression 19.9 The assumptions of regression Like every statistical technique, regression has assumptions that must be true in order for the results of the technique to be valid. We've discussed a few of these already, but we have to add one more assumption: the assumed model ...
run the LinearRegression example but nothing changed, I got the same error. Owner eaplatanios commented Oct 19, 2017 This is interesting. Can you try changing the library dependencies line in your build.sbt file to: libraryDependencies += "org.platanios" %% "tensorflow" % "0.1.0-SNAPSHOT...
