The NLP procedure provides a variety of ways for estimating parameters in nonlinear statistical models and for obtaining approximate standard errors and covariance matrices for the estimators. These ...

In these data sets, the residuals may be correlated across firms or across time, and OLS standard errors can be biased. Historically, researchers in the two literatures have used different solutions ...

Can MLwiN produce robust standard errors? Sandwich estimators for standard errors are often useful, eg when model based estimators are very complex and difficult to compute and robust alternatives are ...

Therefore, X-ray intensities will be reduced relative to a non-inclined, ideal geometry, giving rise to errors in the accuracy of the analysis ... and result in a reduced intensity being collected for ...
