ይህን ትእዛዝ ለ መፈጸም...

#### From the menu bar:

Choose Data - Statistics - Exponential Smoothing

#### From the tabbed interface:

Choose Data - Statistics - Exponential Smoothing.

On the Data menu of the Data tab, choose Statistics - Exponential Smoothing.

Exponential smoothing is a filtering technique that when applied to a data set, produces smoothed results. It is employed in many domains such as stock market, economics and in sampled measurements.

For more information on exponential smoothing, refer to the corresponding Wikipedia article.

## ደንቦች

Smoothing Factor: A parameter between 0 and 1 that represents the damping factor Alpha in the smoothing equation.

#### ለምሳሌ

የሚቀጥለው ሰንጠረዥ ሁለት ጊዜ ተከታታዮች አለው: አንዱ የሚወክለው የ ግፊት ተግባር በ ጊዜ t=0 እና ሌላው የ ግፊት ተግባር በ ጊዜ t=2 ነው
