NettetMoving Averages. Moving averages smooth the time series data to give a clear indication of where the trend is following. Moving averages help smooth the data by eliminating the noise. For calculating the moving average, you will be taking the arithmetic mean of a variable of the data. There are two types of moving averages, and they are … NettetFor a stationary time series, a moving average model sees the value of a variable at time ‘t’ as a linear function of residual errors from ‘q’ time steps preceding it. The …

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). gulf 12
