“…The ARCH model has conditional mean and variance specifications. 𝑅 𝑡 is the dependent variable of the model and represents the return of financial data, whereas the term 𝜎 𝑡 2 represents conditional volatility at time t. In turn, 𝜀 𝑡 it represents a sequence of independent and identically distributed random variables, of zero mean and variance one. The alphas, finally, are the different parameters of the model.…”
