Exponential Smoothing Model

A time series forecasting method that applies weighted averages of past observations, decreasing exponentially as the observations get older.

Mean Square Error

A statistical measure used to evaluate the accuracy of a model by calculating the average squared difference between the estimated values and the actual value.

Smoothing Constant

A Smoothing Constant is a parameter used in exponential smoothing models for forecasting, which controls the weight given to the most recent observation.

Regression Method

A statistical process for estimating the relationships among variables, often used to predict the value of a dependent variable based on one or more independent variables.
