Web2.1 Moving Average Models (MA models) Time series models known as ARIMA models may include autoregressive terms and/or moving average terms. In Week 1, we learned an autoregressive term in a time series model for the variable x t is a lagged value of x t. For instance, a lag 1 autoregressive term is x t − 1 (multiplied by a coefficient). WebPhi Only used on 2x2 contingency tables. Interpreted as a measure of the relative (strength) of an association between two variables ranging from 0 to 1. Pearson's Contingency Coefficient (C) It is interpreted as a measure of the relative (strength) of an association between two variables.
