How to configure mobile hydraulic valves using power beyond
How to configure mobile hydraulic valves using power beyond

What is, power beyond? Power beyond, - also called high-pressure carry over (HPCO), is a facility on a mobile, hydraulic, directional, control valve, which enables the pressure gallery to be isolated from the tank gallery and be carried over to an additional, valve, - usually another directional, control valve., The valve being installed must be sized to handle the rated flow from the pump. The arrangement of the, power beyond, …

Strategic Misspecification in Regression Models
Strategic Misspecification in Regression Models

The problem of strategic ,misspecification, in paramet-ric models is precisely a problem of ,functional, form ,misspecification,, and its proof is analogous to that just demonstrated with the classical linear model. In this ar-ticle, we address strategic ,misspecification, in the context of binary choice models, since binary data is so widely

We demonstrate that this “strategic misspecification” is really an issue of structural (or functional form) misspecification. The misspecification can be equivalently written as a form of omitted variable bias, where the omitted variables are nonlinear terms arising from the players' expected utility calculations and often from data aggregation.
