### HVSR statistical comparison

Posted:

**Thu Mar 22, 2012 6:34 pm**Hi mark, excuse me but I haveanother question.

This question is about the tool Statistical comparison for HVSR

for example:

Frequency peak statistics:

Reference: 0.16 0.18 0.19 Hz Test: 0.14 0.17 0.19 Hz

F-Test (0.95): 0.526946 in [ 0.901066 , 0.947927 ] => NOT similar variances

Student Test (0.95, equal variances): |delta(f0)|=0.0136126 > 0.00971345 => NOT similar peaks

Student Test (0.95, unequal variances): |delta(f0)|=0.0136126 > 0.00771445 => NOT similar peaks

Reference are the picks with St. dev. of H/V ratio and this it's Ok

F-test (0,95) is the confidence that I can chose for my data;

what is: 0.526946 in [ 0.901066, 0.947927]

I know what is F-test but I can't understand what are that numbers

can you help me?
