 In general, useful results for weighted regression are those that remove the correlation of dissolved oxygen, production, and respiration with tidal changes.  Similarly, the mean estimates of metabolism should not change if a long time series is evaluated, whereas the standard deviation and percent anomalous estimates should decrease.

 Plot metabolism results from observed dissolved oxygen time series (see `?plot.metab` for options).  Note the periodicity with fortnightly tidal variation and instances with negative production/positive respiration.
