The aim of the present study was to assess the construct validity of five nutrient profiling systems, using diet modeling with linear programming for designing healthy and unhealthy diets. 3 ...

When thermal simulation software isn't available, or for quicker results, designers can apply linear superposition to model the thermal performance of their power systems. This article is the ...

Comparing regression coefficients between models when one model is nested within another is of great practical interest when two explanations of a given phenomenon are specified as linear models. The ...

We analyze linear panel regression models with interactive fixed effects and predetermined regressors, for example lagged-dependent variables.
