Starting Values Used During a Fit

Discussion

The start_var table contains one value for each of the model_variables . The init_command creates a start_var table using the mean of the priors for the model variables values. The set_command can also be used to create a start_var table. This table may also be created directly by the user (with the aid of the var_table ).

start_var_id

This column has type integer and is the primary key for this table. Its initial value is zero, and it increments by one for each row. The start_var_id column is also a foreign key for the var_table ; i.e.,

var_id = start_var_id

In addition, the size of both tables is the same.

start_var_value

The column has type real and is the value of the model_variables where the optimization procedure is started during the fit_command .

Example

See the init_command.py example and test.
