Coefficient table

Column Name	Data Type	Description
sub_model_id	integer	Identifier for a submodel, if used by the model, or -2 if not used by this model.
coefficient_name	varchar	Unique name of a coefficient
estimate	double	The estimated value of this coefficient
standard_error	double	(optional) The standard error of this estimated value. This is for reference only and is not used by UrbanSim.
t_statistic	double	(optional) The t-statistic of this coefficient for the test of significance from 0. This is for reference only and is not used by UrbanSim.
p_value	double	(optional) The p-value of this t-statistic, gives the Prob(|x|>|estimated coefficient|) when x is drawn from a t-distribution with mean 0. This is for reference only and is not used by UrbanSim.

• sub_model_id must be in the appropriate cross-reference table for each model.
• Each combination of (sub_model_id, coefficient_name) must be unique.
