In this study various types of loss functions and their uses were studied. In this study linex loss function, the analyst’s loss function, the optimal prediction under asymmetric loss, loss functions for forecasting financial returns, loss function and forecast biasedness, loss functions for estimation and evaluation, loss functions for probability forecasts and volatility forecasts have been studied.
