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 ...

Mathematical equations aren't just useful — many are quite beautiful. And many scientists admit they are often fond of particular formulas not just for their function, but for their form, and the ...
