Syntax: @stdevspby(x, y[y1, y2, ... yn, s])
x: series
y series, alpha
s: (optional) sample string or object
Return: series
Returns the population Pearson product moment standard deviations (d.f. corrected) for x each group defined by distinct values of y.
EViews will use the current or specified workfile sample.
Examples
show @stdevpsby(x, g1, g2)
produces a linked series of the by-group population standard deviations of the series x, where members of the same group have identical values for both g1 and g2.
