trend function and null points
Posted: Sun Mar 22, 2009 10:41 am
I have a tlineseries which I am assignning a trend function, the lineseries contains gaps to which I am adding nulls with addnull. When I display the lineseries I have it configured so display shows grpah of curve in x,y, then blank gaps for a few samples where there is null data, then curve continues when there is data. The trend seems to include the null values (period is set to 2), I get a trend where there is contiguous data samples, but trend dives to zero when it hits the null data samples. What's the recommened way of dealing with this please?
