Interim Standings

After eight snow storms... donsutherland1 maintains his near season-long and commanding lead... shanabe and Donald Rosenfeld hold onto second and third...respectively.

Several forecasters ranked in previous Interim Standings had not entered at least six forecasts and were not eligible for this summary under the ‘two-thirds’ rule.

Full interim forecaster error statistics table and charts here.

Forecaster storm summary data 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 two-thirds of their best forecasts are used to calculate Interim and Final standings. Same idea as dropping the lowest quiz score before the final grade is computed.
