27 Calculation algorithm "*QuantileRegression*"
28 --------------------------------------------
33 This algorithm allows to estimate the conditional quantiles of the state
34 parameters distribution, expressed with a model of the observed variables. These
35 are then the quantiles on the observed variables which will allow to determine
36 the model parameters that satisfy to the quantiles conditions.
38 Optional and required commands
39 ++++++++++++++++++++++++++++++
41 The general required commands, available in the editing user interface, are the
44 .. include:: snippets/Background.rst
46 .. include:: snippets/Observation.rst
48 .. include:: snippets/ObservationOperator.rst
50 The general optional commands, available in the editing user interface, are
51 indicated in :ref:`section_ref_assimilation_keywords`. Moreover, the parameters
52 of the command "*AlgorithmParameters*" allows to choose the specific options,
53 described hereafter, of the algorithm. See
54 :ref:`section_ref_options_Algorithm_Parameters` for the good use of this
57 The options of the algorithm are the following:

61 .. include:: snippets/MaximumNumberOfSteps.rst
63 .. include:: snippets/CostDecrementTolerance_6.rst
65 .. include:: snippets/BoundsWithNone.rst
67 StoreSupplementaryCalculations
68 .. index:: single: StoreSupplementaryCalculations
70 This list indicates the names of the supplementary variables that can be
71 available at the end of the algorithm. It involves potentially costly
72 calculations or memory consumptions. The default is a void list, none of
73 these variables being calculated and stored by default. The possible names
74 are in the following list: ["BMA", "CostFunctionJ", "CostFunctionJb",
75 "CostFunctionJo", "CurrentState", "OMA", "OMB", "Innovation",
76 "SimulatedObservationAtBackground", "SimulatedObservationAtCurrentState",
77 "SimulatedObservationAtOptimum"].
80 ``{"StoreSupplementaryCalculations":["BMA", "Innovation"]}``
82 *Tips for this algorithm:*
84 As the *"BackgroundError"* and *"ObservationError"* commands are required
85 for ALL the calculation algorithms in the interface, you have to provide a
86 value, even if these commands are not required for this algorithm, and will
87 not be used. The simplest way is to give "1" as a STRING for both.
89 Information and variables available at the end of the algorithm
90 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
92 At the output, after executing the algorithm, there are variables and
93 information originating from the calculation. The description of
94 :ref:`section_ref_output_variables` show the way to obtain them by the method
95 named ``get`` of the variable "*ADD*" of the post-processing. The input
96 variables, available to the user at the output in order to facilitate the
97 writing of post-processing procedures, are described in the
98 :ref:`subsection_r_o_v_Inventaire`.
