After entering data we can see the graph and trends calculated, choosing the model with a greater degree of fit (coefficient of determination higher). The selected function can be used to make predictions of the variable under study (y), assigning values in function to the time variable (x). It can also be seen in the graph, where there is the trend by adding more data of time (years, months, ...) in the DATE column.

Exponential smoothing is obtained by a moving average with weights declining in geometric progression. Brown's double exponential smoothing, includes a trend component which is useful for forecasting series with or without trend but no seasonality. To achieve optimal prediction we need an ALFA coefficient that minimizes squared error, which is achieved by trying different values between zero and one in the following Excel model.
This technique is used to forecast economic series such as: sales, revenues, costs, expenses, production, wages, economic indicators...
