-[[Table|Tables]] allow simulation data to be presented in a tabular form. The data which is presented by the table can be transformed in different ways, and can be multi dimensionalWhen the dimension of the data is larger than two, columns are split to to provide space.+[[Table|Tables]] allow simulation data to be presented in a tabular form. The correlation table is used after a sensitivity analysis to present correlation coefficients between model inputs and model outputsThe table is only available after a probabilistic simulation or a sensitivity analysis has been performed.
  
-For a general table, the following dimensions are possible:+For a correlation table, the following dimensions are available:
  
   * **Outputs** - The outputs that have been selected for the table.   * **Outputs** - The outputs that have been selected for the table.
-  * **Statistics** - If the data is probabilistic, then statistics can be presented in an extra dimension. It is also possible to display data for specific (or all) iterations. +  * **Time** - If any of the outputs is time dependent, then the time dimension allow you to select which time points to show data for. It is also possible to show the minimum/maximum value across the time vector and the time points for which the minimum or maximum occurs.
-  * **Time** - If any of the outputs is time dependent, then the time dimension allow you to select which time points to show data for. It is also possible to show the minimum/maximum value across the time vector or the time points for which the minimum or maximum occurs.+
   * **Indices** - For each dimension of the selected outputs, a dimension is available for the table data. These dimensions allow you to select all, or only a sub-set of the indices of an [[Index list|index list]].   * **Indices** - For each dimension of the selected outputs, a dimension is available for the table data.

 To edit a correlation table either right-click the table in the [[Tables_window|tables window]] and select **Edit**, or double-click the table, or click the {{:Edit24.png|Edit}} button in the title bar. To edit a correlation table either right-click the table in the [[Tables_window|tables window]] and select **Edit**, or double-click the table, or click the {{:Edit24.png|Edit}} button in the title bar.
  
 +The table editor has the following tabs:
  
- +  * **Outputs** - Select which outputs to include in the table. The outputs should all have the same dimension.  
-The table editor has two tabs: +  * **Indices** - Depending on the dimension of the outputs that were selected, you can select which indices to include or to include all indices
- +  * **Time** - If the outputs are time dependent, this tab allows you to select which time points to display data for.  
-==== Properties ==== +    * **Specific** - Select either all time points or specific time points to include 
- +    * **First** - Display the first time point 
-This screen let you edit properties such as name, that are common to all tables. Please see [[Editing_table_properties|editing table properties]] for more information. +    * **Last** - Display the last time point 
- +    * **Max over time** - Display the maximum value for each output over time  
-==== Data ==== +    * **Time for max** - Display the time point for the maximum value for each output 
- +    * **Min over time** - Display the minimum value for each output over time  
-This page lets you choose which outputs to include in the table. +    * **Time for min** - Display the time point for the minimum value for each output 
- +  * **Correlation** - This tab allows you to select which coefficients to calculate and how to transform the data
-**Rows** +    * **Correlation** - Select which coefficients to calculate 
- +    * **Transformation** - Select how to transform the data before coefficients are calculated. Note that transformation is sometimes already performed by the selected correlation. For instance, [[Spearman]] is the same as [[Pearson]] with ranked data. 
-  * **Title** – Enter a name for the first column. The default name is Inputbut you are free to enter any text here+    * **Inputs** - Select whether to include all selected parameters, or to filter out parameters that cannot influence the selected outputs.
