Asymptotic properties of the weighted average least squares (WALS) estimator

De Luca, Giuseppe; Magnus, Jan; Peracchi, Franco - 2022

We investigate the asymptotic behavior of the WALS estimator, a model-averaging estimator with attractive finite-sample and computational properties. WALS is closely related to the normal location model, and hence much of the paper concerns the asymptotic behavior of the estimator of the unknown...

Getting the Right Tail Right: Modeling tails of health expenditure distributions

Karlsson, Martin; Wang, Yulong; Ziebarth, Nicolas R. - 2023

Health expenditure data almost always include extreme values, implying that the underlying distribution has heavy tails. This may result in infinite variances as well as higher-order moments and bias the commonly used least squares methods. To accommodate extreme values, we propose an estimation...

Non-Standard Errors*

Bosch-Rosa, Ciril; Kassner, Bernhard - 2023

In statistics, samples are drawn from a population in a data-generating process (DGP). Standard errors measure the uncertainty in estimates of population parameters. In science, evidence is generated to test hypotheses in an evidence-generating process (EGP). We claim that EGP variation across...
