Generalized Error Distribution

Error

⎊ The Generalized Error Distribution (GED) represents a flexible family of probability distributions, extending the normal distribution to encompass a wider range of tail behaviors crucial for modeling financial asset returns. Its utility in cryptocurrency, options, and derivatives stems from its capacity to capture leptokurtosis—the tendency for extreme values to occur more frequently than predicted by a normal distribution—a common characteristic of these markets. Parameter estimation, often employing maximum likelihood techniques, allows for calibration to observed market data, enhancing the accuracy of risk assessments and pricing models.
