RE: [GT] Input validation in Tools.pm

["Weigert, Thomas" <weigert AT mst.edu>]

Linear regression is used typically in two ways:

1. estimate future values of an indicator based on curve fitting of past
values. (See the discussion in Chande, "The New Technical Trader" 1994.)

2. determine whether an indicator has reached a peak or trough and
turned around (the slope of the linear regression changes sign).
