Is the POLYCONF function computing the confidence interval or the prediction interval in the Statistics Toolbox 5.0.1 (R14SP1)?

When I type "doc polyconf" at the MATLAB command prompt, the documentation states that POLYCONF computes a confidence interval. However, when I type "help polyconf" at the MATLAB command prompt, the file help indicates that POLYCONF computes a prediction interval.

This enhancement has been incorporated in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This has been verified as an error within the documentation for POLYCONF within the Statistics Toolbox 5.0.1 (R14SP1). The POLYCONF function computes the prediction interval, not the confidence interval.
