EXPONENTIALSMOOTHING(Array, DampingFactor, ShowChart, ShowStandardErrorOptions, NewTableFlag)


  • where, is the input array or reference to the cells containing array,
  • is a corrective factor that minimizes the instability of data,
  • is a logical value that decides whether to display a chart,
  • is a logical value that decides whether to calculate standard errors,
  • is a logical value that decides whether to display the output in the same worksheet or a new space cube.
    • EXPONENTIALSMOOTHING(), Smooths data, weighting more recent data heavier.

Description

EXPONENTIALSMOOTHING(Array, DampingFactor, ShowChart, ShowStandardErrorOptions, NewTableFlag)

  • Exponential Smoothing is a technique that can be applied to a set of data, either to produce smoothed data for presentations, or to make forecasts.
  •   should be array of numbers.
  •   is the exponential smoothing constant referred as α. Value of α should be greater than '0'.
  • If   < 0, Calci displays #NULL error message.
  • Smaller the damping factor, more smoother are the projections.
  • If   is omitted, Calci assumes it to be '0.3'.
  •   can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
  •   can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
  •   can be a logical value TRUE or FALSE. If omitted, Calci assumes it to be FALSE.
  • If   is TRUE, the result is displayed on new zspace sheet.

ZOS

  • The syntax is to use this function in ZOS is  
  • For e.g.,EXPONENTIALSMOOTHING([10,12.3,18,9.4,22,39,45,51,29],0.5,true,false,true)
