# Enable Information Component Calculation for Signal Detection

With the 26R1 release, Vault supports the Information Component (IC) advanced calculation for disproportionality reporting. _Signal Calculations_ using the IC statistical method offer high confidence when detecting _Product-Event Combinations_ (PECs) in small sample sizes. After you have configured this feature, see the following articles for more information:
* <a href="/en/lr/753144/">Configure Signal Calculation Objects</a>
* <a href="/en/lr/752951/#ic">Signal Detection Calculations</a>
* <a href="/en/lr/935435/#data">Create Statistical Data</a>

## Update Object Layouts

Update the following <a href="/en/lr/26387/#how-to-access-page-layouts">object layouts</a>:
* [_Statistical Data_][1]
* [_Signal Calculation_][2]

### Statistical Data Layout {#statistical-data}

To update the _Statistical Data_ object layout, <a href="/en/lr/26387/#how-to-add-object-fields">add</a> the following fields to the _Data_ section:
* _IC_
* _IC-Bayes_
* _IC005_
* _IC025_
* _Prior Used_

### Signal Calculation Layout {#signal-calculation}

To update the _Signal Calculation_ object layout, in the _Details_ section, <a href="/en/lr/26387/#how-to-add-object-fields">add</a> the _Prior Used_ field after the _Calculation_ field. Then, create a <a href="/en/lr/51632/#creating-layout-rules">layout rule</a> for the _Prior Used_ field with the following configuration: 
* **Label**: Enter `Hide if not IC`.
* **IF this Layout Rule Expression is TRUE**: Enter `Not(calculation__v = 'ic__v')`.
* **Apply the following display effects**: Select **Hide > Fields > Prior Used**.
