keskiarvoeron

Keskiarvoeron is a statistical term that refers to the average error of a model's predictions. It is a measure of how well a model fits the data, with a lower keskiarvoeron indicating a better fit. The term is often used in the context of regression analysis, where it is used to evaluate the accuracy of a regression model.

Keskiarvoeron can be calculated in a number of ways, but the most common method is to take the average of the absolute differences between the predicted values and the actual values. For example, if a model predicts that a house will sell for $300,000 and it actually sells for $320,000, the error is $20,000. If the model predicts that another house will sell for $400,000 and it actually sells for $390,000, the error is -$10,000. The keskiarvoeron would be the average of the absolute values of these errors.

Keskiarvoeron is a useful metric for evaluating the performance of a model, but it is not the only metric that should be considered. Other metrics, such as R-squared and mean squared error, can also be used to assess the quality of a model. It is important to use a variety of metrics when evaluating a model, as each metric provides a different perspective on the model's performance.
