Without variables, programming languages are next to useless. Fortunately, JavaScript’s variable system is incredibly powerful and versatile.

Mathematical programming discriminant analysis models must be normalised to prevent the generation of discriminant functions in which the variable coefficients and the constant term are zero. This ...

The idea of variables, program flow, loops, and arrays all have some parallel in just about anything, so we can see some advantages to starting out simply. After all, you don’t learn to drive by ...

In the first part of this paper, the concept of logical reduction is presented. Minimal preferred variable inequalities are introduced, and algorithms are given for their calculation. A simple ...

Programming statements are used to create or modify the values of the explanatory variables in the MODEL statement. They are especially useful in fitting models with time-dependent explanatory ...
