# Accuracy Indicator

### Explanation

When issuing a model-based valuation, the model supplier must specify every model-based valuation appraisal value with an indication of the accuracy of the individual concerned transaction value. A seven-point scale is used for accuracy, which is based on the probability distribution around the value. The following classification applies:

### Classification

<table><thead><tr><th width="196">Accuracy Indicator</th><th>Definition</th></tr></thead><tbody><tr><td>0</td><td>&#x3C;50% accuracy in 20% deviation</td></tr><tr><td>1</td><td>&#x3C; 85% accuracy in 20% deviation</td></tr><tr><td>2</td><td>>= 85% accuracy in 20% deviation</td></tr><tr><td>3</td><td>>= 85% accuracy in 20% deviation and >= 70% accuracy in 10% deviation</td></tr><tr><td>4</td><td>>= 85% accuracy in 20% deviation and >= 80% accuracy in 10% deviation</td></tr><tr><td>5</td><td>>= 85% accuracy in 20% deviation and >= 85% accuracy in 10% deviation and >= 60% accuracy in 5% deviation</td></tr><tr><td>6</td><td>>= 90% accuracy in 20% deviation and >= 90% accuracy in 10% deviation and >= 70% accuracy in 5% deviation</td></tr><tr><td>7</td><td>>= 95% accuracy in 20% deviation and >= 90% accuracy in 10% deviation and >= 80% accuracy in 5% deviation</td></tr></tbody></table>

Depending on the purpose of the model-based valuation, it is determined which level of accuracy minimum is required.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.altum.ai/english/property-valuation-and-market/avm-api/accuracy-indicator.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
