Is there an error in the documentation for the TSMOVAVG function from the Financial Time Series Toolbox 2.0 (R13)?

I am using the following syntax:

   tsmovavg(x,'s',LEAD,LAG,DIM),

where lead and lag refers to number of previous and following data points.

The documentation, however, says:

LEAD: Number of following data points

LAG: Number of previous data points

This bug has been fixed for Release 14 (R14). For previous releases, there is an error in the documentation and the help section in the program file.

LEAD and LAG actually refer to number of previous and following data points, respectively.

The documentation should read:

 output = tsmovavg(vector, 's', lag, dim) compute the simple moving average. lag indicates the number of previous data points used in conjunction with the current data point when calculating the moving average.
