GRIDSERIES Procedure

@GRIDSERIES creates a series with an evenly spaced grid of values.

@GridSeries(options) grid

Parameters

grid	(output) series to be created

Options

N=number of intervals [100]

FROM=lower limit

TO=upper limit

SIZE=size of intervals

At least two from FROM, TO and SIZE are needed to determine the grid. If you provide all three, then they will also determine the number of intervals so N will be ignored.

PTS=(output) number of grid points

Note that the number of grid points is one more than the number of intervals.

Examples

@gridseries(from=-6.0,to=6.0,size=.001,pts=gpts) xgrid

defines a grid running from -6 to +6 with an interval width of .001. XGRID will have 12001 points (GPTS will be equal to 12001).

stats(fract) xki

compute ngrid=200

@gridseries(from=%fract01,to=%fract99,n=ngrid) u

creates in the series U a 200 interval grid running from the 1%-ile to the 99%-ile of the XKI series.
