STEYX (KnownYs,KnownXs)


  • is set of dependent values.
  • is the set of independent values.
    • STEYX(),returns the standard error of the predicted y-value for each x in the regression.

Description

  • This function gives the standard error of the regression, which also is known as the standard error of the estimate.
  • It is calculates the standard error for the straight line of best fit through a supplied set of   and   values.
  • The standard error for this line provides a measure of the error in the prediction of   for an individual  .
  • The equation for the standard error of the predicted   is:

  where   and   are the sample mean   and  .

  • In  ,   is the array of the numeric dependent values and   is the array of the independent values.
  • The arguments can be be either numbers or names, array,constants or references that contain numbers.
  • Suppose the array contains text,logical values or empty cells, like that values are not considered.
  • This function will return the result as error when
  1. Any one of the argument is non-numeric. 
  2. KnownYs and KnownXs are empty or that have less than three data points.
  3. KnownYs and KnownXs  have a different number of data points.
