# Macro "**sensitivityRegressionFunctionFlowrate.{{extension}}**"

## Objective

The objective of this macro is to perform a regression with "SRC" method on a database generated with 
a function using sampling of parameters obeying uniform laws with 4000 patterns. `flowrateModel` is 
a function defined in [](#launcher_introduction_simple_case_problem) and "loaded" through the macro 
`UserFunctions.C` (the file can be found in `${URANIESYS}/share/uranie/macros`). Function 
`flowrateModel` uses the eight variables defined in [](#launcher_introduction_simple_case_problem) 
and set in the main macro.

## Macro {{uranie}}

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + macro[language] + "\n"
    + "```"
}}
            
Each attribute is related to a `TAttribute` obeying uniform laws on specific intervals:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc1[language] + "\n"
    + "```"
}}
            
The sampling is generated on 4000 patterns with a LHS method:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc2[language] + "\n"
    + "```"
}}
            
Function `flowrateModel` is set to perform calculation on the sampling:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc3[language] + "\n"
    + "```"
}}
            
The regression is performed over all variables:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc4[language] + "\n"
    + "```"
}}
            
Sensitivity indexes are then displayed through an histogram:

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/uranie/doc/sensitivity/use_cases/" + language + "/sensitivityRegressionFunctionFlowrate." 
        + extension
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc5[language] + "\n"
    + "```"
}}
            
## Graph

{{
    "```{" "figure" "} " + parent_dir +
        "/roottest/build/uranie/doc/sensitivity/use_cases/" + language 
        + "/regression/sensitivityRegressionFunctionFlowrate.png\n"
    + ":align: center\n"
    + ":name: use_cases_sensitivityRegressionFunctionFlowrate\n"
    + figure_scale + "\n"
    + "\n"
    + "Graph of the macro **\"sensitivityRegressionFunctionFlowrate." + extension + "\"**" + "\n"
    + "```"
}}
            
## Console

{{
    "```{" "literalinclude" "} " + parent_dir +
        "/roottest/build/uranie/doc/sensitivity/use_cases/" + language 
        + "/sensitivityRegressionFunctionFlowrate_clean.log"
    + "\n"
    + ":language: none\n"
    + ":lines: " + console[language] + "\n"
    + "```"
