Syntax
>>> TORNADO (: n_std_dev / BOUNDS)
Parent Command
>> OPTION
Subcommand
-
Description
This command generates a Tornado plot by evaluating the objective function at a reference parameter set (i.e., the initial guess) and at discrete points along each of the parameter axes. By default, two additional points per parameter are evaluated by adding and subtracting one standard deviation (as specified by commands >>>> VARIATION or >>>> DEVIATION in block > PARAMETER) from the reference parameter set. Additional points can be requested as n_std_dev multiples of the standard deviation. Alternatively, points at the lower and upper BOUNDS as specified in command >>>> RANGE in block > PARAMETER are evaluated. To obtain a Tornado plot of a particular prediction, use >>>> ZERO DATA and >>> L1-ESTIMATION.
