residuaalimallin
Residuaalimallin, often translated as residual model or residual analysis, is a statistical concept used to evaluate the performance of a model, particularly in regression analysis. It involves examining the differences between the observed values of the dependent variable and the values predicted by the model. These differences are known as residuals. The primary goal of residual analysis is to identify systematic patterns or deviations in the residuals that suggest the underlying model assumptions are violated or that the model itself is inadequate.
Commonly, residuals are plotted against the predicted values or against independent variables. A well-fitting model will
Interpreting residual plots helps in refining the model. For instance, a curved pattern might suggest that
