Set the value, limits and distribution of a model constant

Syntax


set <constant name 1> = <value 1> <constant name 2> = <value 2>

set <constant name> = <value> …

   @min=<value> @max=<value> …

   @dist=<distribution> @mean=<value> @std=<value>

Description


The SET command is used to set the value of model quantities defined using the CONSTANT statement.  Additionally, the SET command can be used to assign upper and lower limits to model parameters for use in parameter estimation studies, or to assign statistical distributions for use in Monte Carlo studies.  The use of the SET command in parameter estimation is detailed in the FIT topic.  The use of the SET command for Monte Carlo analysis is detailed in the START topic.


Flags are used to set the limits and statistical settings as follows:


@min=<value>

The lower limit to be associated with this parameter

@max=<value>

The upper limit to be associated with this parameter

@dist=<distribution>

The statistical distribution to be associated with this parameter (one of: unif, norm, logn for unform, normal and lognormal respectively).

@mean=<value>

The mean of the statistical distribution associated with the @dist flag

@std=<value>

The standard deviation of the statistical distribution associated with the @dist flag


Example


set pc_pp=1.4 @dist=norm @mean=1.4 @std=0.3

set k1 = 0.0  k2 = 0.3  k3 = 1.5
