Compute deviations from the mean of the series.
Syntax: @demean(x[, s])
x: series, vector, matrix
s: (optional) sample string or object when x is a series and assigning result to a series
Return: series, vector, matrix
Returns a copy of x after subtracting off the mean.
For series calculations, EViews will use the current or specified workfile sample.
This function is panel aware.
Examples
The code below produces a graph of a series and its demeaned form:
wfcreate m 2000 2020
series y = 10 + nrnd
group g y @demean(y)
g.line
The first line creates a monthly workfile starting in January 2000 and ending in December 2020. The second line generates a series y equal to 10 plus normal error. The last two lines graphs y and @demean(y) together.
