Accurately modeling particle movement through fluids is crucial in fields ranging from chemical engineering to aerospace. The drag coefficient, which influences how particles settle and move in fluid ...

I have estimated an RC model and then attempted to run a simulation using the results by changing some values in a dummy variable from 0 to 1. I encountered a similar problem to issue #119 where the ...

Adaptive fractional polynomial modeling of general correlated outcomes is formulated to address nonlinearity in means, variances/dispersions, and correlations. Means and variances/dispersions are ...

In this paper, a model averaging method is proposed for varying-coefficient models with response missing at random by establishing a weight selection criterion based on cross-validation. Under certain ...

A reader wonders why we rarely see smiles on the catwalk — and if that’s always been the case in fashion. By Vanessa Friedman Why do runway models always look miserable? They always look as if they ...

The facelifted Tesla Model 3 is here and there's a lot to talk about even though one might be tempted to believe we're dealing with an average mid-cycle nip and tuck. Besides the styling and equipment ...
