Displaying Predictions
----------------------

   GroupLens makes a prediction for you about how much you will like a
news article.  The predictions from GroupLens are on a scale from 1 to
5, where 1 is the worst and 5 is the best.  You can use the predictions
from GroupLens in one of three ways controlled by the variable
`gnus-grouplens-override-scoring'.

   There are three ways to display predictions in grouplens.  You may
choose to have the GroupLens scores contribute to, or override the
regular gnus scoring mechanism.  override is the default; however, some
people prefer to see the Gnus scores plus the grouplens scores.  To get
the separate scoring behavior you need to set
`gnus-grouplens-override-scoring' to `'separate'.  To have the
GroupLens predictions combined with the grouplens scores set it to
`'override' and to combine the scores set
`gnus-grouplens-override-scoring' to `'combine'.  When you use the
combine option you will also want to set the values for
`grouplens-prediction-offset' and `grouplens-score-scale-factor'.

   In either case, GroupLens gives you a few choices for how you would
like to see your predictions displayed.  The display of predictions is
controlled by the `grouplens-prediction-display' variable.

   The following are valid values for that variable.

`prediction-spot'
     The higher the prediction, the further to the right an `*' is
     displayed.

`confidence-interval'
     A numeric confidence interval.

`prediction-bar'
     The higher the prediction, the longer the bar.

`confidence-bar'
     Numerical confidence.

`confidence-spot'
     The spot gets bigger with more confidence.

`prediction-num'
     Plain-old numeric value.

`confidence-plus-minus'
     Prediction +/- confidence.
