Moreover, we will look at the significance of **known_y’s** and the purpose of **new_x’s** in FORECAST.ETS. So, letâ€™s unlock the full potential of FORECAST.ETS!

### Exploring x-values with FORECAST.ETS

If you have **x-values** that refer to the period that your data covers, you can use them with **FORECAST.ETS** to anticipate future trends. This tool will study old values and compute a forecast for each x-value in the group.

To get the forecast results, one parameter you should consider is the **confidence interval**. It shows how probable the expected results are, based on stats of past values.

Another parameter is the **smoothing constant**. It controls how much importance to give recent and old data. Finding the correct balance between recent and past data points is vital for exact predictions.

**Tip:** To get better results from **FORECAST.ETS**, try various combinations of confidence intervals and smoothing constants to find the one that works best for your data.

Then, let’s look at the importance of another parameter in **FORECAST.ETS – known_y’s** – and how they influence predicting future outcomes.

### Known_y’s and Their Impact

**Excel’s FORECAST.ETS formula** is a powerful tool for any business that needs to forecast future values. It requires the input of *“known_y’s”* – the series of past or historical values. The accuracy of known_y’s is crucial, as they form the foundation for future projections.

For example, consider a delivery company that wants to predict fuel needs for the next quarter. Accurate and reliable data in the historical records will lead to precise forecasts. But, if the data is incomplete or inaccurate, the forecasts may be unreliable.

Take another scenario – inputting gas prices from past quarters without accounting for inflation or external factors. This can lead to inaccurate predictions and undesirable results like running out of fuel before completing deliveries or overordering fuel.

We also have *new_x’s* in FORECAST.ETS. They refer to future values or dates where forecasts will be made after creating projections based on past data using known_y’s parameters.

### The Role of New_x’s in FORECAST.ETS

The “**new_x’s**” parameter is very relevant when using the FORECAST.ETS function in Excel. This parameter stands for the range of new x-values for which we want to forecast corresponding y-values. It helps us forecast future data points based on past trends.

To comprehend “**new_x’s**” better, let’s make a table:

New_x’s | Explanation |
---|---|

Range of cell references | Specifies x-values for which we want to forecast y-values. |

Can be non-contiguous | The range can have multiple non-contiguous areas. |

Must be same size as known_y’s | The number of cells must match or exceed the number of cells in the known_y’s range. |

We cannot make accurate forecasts without the “**new_x’s**” parameter. Microsoft suggests that typically, the function requires four seasons of historical data to give meaningful results.

It is important to understand that Excel can only be used as a starting point for further investigation and decisions. It should not be used solely for making essential business decisions.

---|---|---|---|

TREND | Forecast future values from past data | Array of known y-values, array of known x-values, new x-values for prediction | Array of predicted y-values |

FORECAST.ETS |
Forecast future values from past data using ETS algorithm |
Range of known y-values, range of known x-values, new x-values for prediction | Single predicted value |

LINEST |
Calculate trendline coefficients for prediction | Array of known y-values, array of known x-values | Array containing slope and intercept coefficients |

As seen from this table, **TREND** and **FORECAST.ETS** are similar yet have different inputs and outputs. **LINEST**, however, calculates trendline coefficients rather than predicting values.

When deciding which function to use, think of your data and what type of output is needed. **FORECAST.ETS** is best for precise numeric predictions. But if you need an array of predicted values based on multiple inputs, **TREND** may be better.
