The Integrand Table#

Discussion#

The integrand table is used to identify data integrands. It has the following columns:

integrand_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.

minimum_meas_cv#

This column has type real and is non-negative and less than or equal one. It specifies the minimum coefficient of variation for measurement values with this integrand. To be specific; for the data table integrand_id is the same, meas_value is the measurement value, and meas_std is the measurement standard, the minimum cv measurement standard deviation is

Delta = max ( meas_std , minimum_meas_cv * | meas_value | )

see Delta in the data likelihood section.

integrand_name#

This column has type text . The following is a list of the possible values for integrand_name . This column is unique; i.e., each name can only appear once in this table. All of the integrand_id values that appear in the data and avgint tables need to appear in the integrand table.

ODE#

If the column ODE below is yes, and a data point has a rate covariate that is not equal to its reference value, the Differential Equation needs to be solved for each cohort that intersects or surrounds the age-time span for this data point. (The space between cohorts is determined by the ode_step_size .)

This computation is preformed each time the model_variables change.
