Syntax: @sumsqsby(x, y, [s])
x: series
y series, alpha
s: (optional) sample string or object
Return: series
Compute the sum of squared observations in x for group identifiers defined by distinct values of y.
EViews will use the current or specified workfile sample.
Examples
show @sumsqsby(x, g1, g2)
produces a linked series of by-group sums of squares of observations in x, where members of the same group have identical values for both g1 and g2.
