Hello Everyone,

I'd like to create some custom moving average functions that retain the 
same length as the original series by padding the lost observations 
with zeros.  I can get the moving average part of the function to work 
but not the padding part.

This part without padding works:

MA[theSeries_, theWindowSize_] = MovingAverage[theSeries,
     theWindowSize];

But adding the padding causes it to fail:

MA[theSeries_, theWindowSize_] = PadLeft[MovingAverage[theSeries,
     theWindowSize], 1000];

Any suggestions would be most appreciated.

	Greg
