**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`.

**Example**

` > COMPUTATION
>> OPTION
>>> generate TORNADO plot at +/- : 3 standard deviations
