The overall context is time series analysis. Let’s sort out the terminology… Scedasticity Scedasticity (or skedasticity) is the distribution of error terms (of some random variable). If the variance (and standard deviation) of the error … Continue reading Generalized AutoRegressive Conditional Heteroscedasticity
