Data for this example are generated. General-form equations are estimated and forecast using PROC MODEL. The system is a basic supply-demand model. Portions of the output from the following code is ...
If the same system is expressed as the following general-form equation, then this equation is used unchanged. EQ.y = y - a + b*x; This makes it easy to solve for ...
A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...
