A time series model where the current value is based on a linear combination of the previous value and a stochastic error term.

Nonautocorrelated Random Error

Errors in a dataset that occur randomly and are not correlated with each other, indicating no predictable pattern in the fluctuations.

Autoregressive Model

An Autoregressive Model is a statistical model for analyzing and forecasting time series data, where future values are assumed to be a linear function of past values.

Exponential Smoothing Model

A forecasting technique that applies decreasing weights to past data, with the most recent data weighted most heavily.
