The length of an index

Finding the length of an index is obviously pretty trivial. But there are several ways to do find it, and there are some “gotchas” if you aren’t careful. The IndexLength function is, of course, the recommended and reliable way to get it. But are you in the habit of using Size(I)? Did you know that Size(I) is not the same as IndexLength(I), and is not always the length of the index? Watch the video to understand the differences.

The free edition of Analytica includes these key Analytica features: 

Free Analytica has no time limit. The only constraint is it won’t let you create more than 100 variables or other objects. But your model can be quite substantial since each variable can be a multidimensional array.  It also lets you explore, change inputs, and run existing models of any size (excluding features unique to the Enterprise or Optimizer editions).

Analytica runs on any Windows computer, or on a Macintosh using Parallels or VMWare.
