Auto-Regressive (AR) Auto-Regressive (AR) is a stationary stochastic process where the current value of the time series is related to the past p values, where p is any integer, is called an AR(p) process. When the current value is related to the previous two values, it is an AR(2) process. An AR(1)
Auto-Regressive Conditional Heteroskedasticity (ARCH) Auto-Regressive Conditional Heteroskedasticity (ARCH) is a nonlinear stochastic process, where the variance is time-varying, and a function of the
past variance. ARCH processes have frequency distributions which have high peaks at the mean and fat-tails, much like fractal
