# Multiple Linear Regression (ML\_R\_2)

The method uses a linear technique to describe the relationship between the variables, and the coefficients of the equation are determined by minimizing the sum of the squared differences between the observed values of the dependent variable and the values predicted by the equation. 

It's a way to analyze multiple factors and understand how they influence a certain outcome.

## Sample Request

Build a multiple linear regression model named, *"SimpleModel"*

```javascript
{
    "project_id": 1,
    "parent_id": 7,
    "block_id": 8,
    "function_code": "ML_R_2",
    "args": {
        "model_name": "SimpleModel"
    }
}
```
