The fixed effects objective
and constraints are scaled using their values at the
model_variables
corresponding to the scale_var table.
The init_command
creates a scale_var table
using the mean of the priors for the model variables values.
The set_command
can also be used to change the start_var table.
This table may also be created directly by the user
(with the aid of the var_table
).
integer
and is the primary key for this table.
Its initial value is zero, and it increments by one for each row.
The
scale_var_id
column is also a foreign key for the
var_table
; i.e.,
var_id = scale_var_id
In addition, the size of both tables is the same.
real
and is
the value of the model_variables
used to scale the likelihood function during the fit_command
.
To be specific, the fixed effects objective function is scaled so that its
derivative is order one at this value of the model variables.
The random effects objective is not currently scaled and so that
value of the random effects does not matter (currently).
