standard deviation

[gaetano.riccio]

Hi,
I would like to ask if geopsy, when calculating the standard deviation for H/V, divides by the number of windows or by the number of windows minus 1 as in the sample standard deviation.

Thanks in advance, regards.

Hi Gaetano,

The amplitude average and standard deviation are calculated on a log scale. The standard deviation uses the number of windows minus 1.
The statistics on the peak frequency follow the same rules.

Best regards,

Marc
