Analysis of flare data
Posted by Roger Hunter on November 01, 2003 at 13:44:37:

Hi all;

I've done a chi-square calculation of the flare/quake data as follows;

I took the cumulative daily totals for 25 flares (#3 is too recent) for mag 5+ quakes as the observed. Expected is 47036 quakes divided by 11233 days times 25 instances.

Chi-square is 80.73 which is off the charts.

VERY significant.

Which means that the observed frequencies do not fit an average number per day value.

Any suggestions?

Roger
