Winter '12 / '13 - Interim Standings: 2

After four storms...it/s Brad Yehl...herb @maws...and dryslot.

Under the ‘two-thirds’ rule…forecasters who have entered at least three forecasts are included in these interim standings.

Full forecaster statistics table and charts here.
All forecasts from all forecasters for all storms here.

SUMSQ errors for each contest snow storm are normalized with a 'Z-score'...then averaged to compute the standings. Forecasters who have entered at least 2/3 of all snow storm contests are included in the standings.

If a forecaster has participated in more than two-thirds of all snow storm contests...then Z-scores from their 'best two-thirds' forecasts are used to calculate Interim and Final standings. Same idea as dropping the lowest quiz score before the final grade is computed.
