Explained: IMsFormulaTerm;
The Explained property returns output series.
Executing the example requires a modeling container with the CONT_MODEL identifier. Five modeling variables with the SOURCE_LRX, RESULT_LRX, AVAL_LRX, APD_LRX, and W1_LRX identifiers must be available in this container.

After executing the example a model with the NEW_LRX_MODEL identifier that uses the LRX-filter method for calculation is created in the modeling container. The output variable, loaded variable, prior values and differences, weights 1, smoothing and residual load parameters, and missing data treatment method are determined for the model.
