It will calculate the linear trend line to the arrays of known y’s and known x’s and extends the linear trendline to calculate additional y-values for an additional supplied data. mehrere Monate) anwenden, wenn Sie die TREND Funktion als Matrixfunktion nutzen. Sie können die TREND Funktion auch direkt über mehrere Zeiträume (z.B. The AVERAGE function will automatically ignore text values and empty cells, so it will continue to calculate an average with fewer values. The TREND function (Excel forecast function) is categorized under statistical functions. Die Excel TREND Funktion gibt Werte auf Basis eines linearen Trends zurück. This may or may not be an issue, depending on the structure of the worksheet, and whether it's important that all averages are based on the same number of values. Weighted Moving Average (WMA) Let’s say that the weather is getting cooler with every passing day and you are using a 10-day moving average to get the temperature trend. Your plot should now look like the one shown opposite. If you start the formulas in the first row of the table, the first few formulas won't have enough data to calculate a complete average, because the range will extend above the first row of data: In Excel, you can do this easily using the AVERAGE function (this is covered later in this tutorial). Select a suitable trendline (with equation) and then click Close. When the values are plotted in a line chart, the smoothing effect is clear:
As the formulas are copied down the column, the range changes at each row to include the values needed for each average. = AVERAGE (C5:C7 ) // 5-day average = AVERAGE (C5:C11 ) // 7-day averageĪll formulas use a relative reference for the range supplied to the AVERAGE function.
