Facebook insights, page_fans_country accessible, no data for page_fans, page_fans_locale or page_fans_gender_age -

-

i'm using fql access pages insights , i've got different results depending on metric pass in query.

for exemple, query works correctly, datas facebook pages :

select value insights object_id='pageid' , metric='page_fans_country' , end_time=end_time_date('2013-04-14t07:00:00+0000') , period='0'

but if use metric page_fans_gender_age or page_fans_locale, don't data, except 1 specific page (which maybe related token).

i don't understand why metric working differently, don't see specific infos in graph documentation ?

are page_fans_country insights datas "public" not other metrics ?

can token problem ? or depend on end_time parameters ?

is problem related bug : https://developers.facebook.com/bugs/345809555540652?browse=search_5148c3f9aa0392220388804

yes - page_fans_country publicly available, other metrics require appropriately authenticated token. it's worth, don't think 0 valid period, either.

normally can avoid end_time issues selecting date few days in past (insights has variable lag time, around 3 days).

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
