Simple-Sales-Forecasting

What it does

A simple and lightweight library to forecast sales that represent a time series.

How to use it

Just import the module and run the imported function passing three arguments:

• An array with all the sales figures.
• The number of predicted values that you want.
• The number of items that a cycle last (in the case of sales monthly figures, a cycle last 4 months).

The function will return an object with two arrays, time, that contains the number of the month of the forecasted values, and predictions, that contains the forecasted values.

Typical Example

const forecastedValuesObject = simpleSalesForecasting(
  [13409, 29389, 128940, 490059, 290394, 1928904, 3892019, 2903945],
  2,
  4
);

/* forecastedValuesObject will contain the following object
{time: [9,10],
predictions: [1119417.565906914, 5144032.282721207]
This means that the 9 month have a forecasted sales figure of $1,119,417 and the 10 month have a forecasted sales figure fo $5,144,032
