{% hint style="info" %}
Before configuring the model, understand how the anomaly is detected:
The model calculates the variation in consumption between the current date **(D0)** and the model date **(D-1, D-7 and D-14)** and checks if the variation is above the value ($) or % configured in the **global** model or in each of the models **by account**.
**D-1**: Date of the previous day
**D-7**: Date of 7 days ago
**D-14**: Date of the last 14 days (average of the period)
Now, choose the model that best suits your needs:
{% endhint %}
{% tabs %}
{% tab title=" Global" %}
* It prevails over all accounts and applies the 3 models D-1, D-7 and D-14
{% endtab %}
{% tab title="By Acount " %}
* It prevails over a specific account and allows the choice of the model to be applied D-1, D-7 and or D-14
{% endtab %}
{% endtabs %}
4. Configure the model:
* **Global**
