2017年12月3日 · At lag=12 you will have the lowest correlation of the day, after what it will begin to increase. Move forward 6 month to 1 pm. Your time series is still somewhat correlated. Move lag to 6 months and 1 am. This might be your lowest correlation point in the time series. At lag of 12 months your timeseries is again close to the peak value.

Zero lag means pairing elements in the series at a common time point which is exactly what you are doing with your Pearson correlation estimation approach. Unfortunately I do not see a good way to use information from data that is missing one of the elements of the pairs.

2019年4月6日 · An autocorrelation asks to what degree realizations with a certain time difference - a lag - co-move. For example, the autocorrelation with a lag of 1 would compute the correlation of the following pairs: $(x_1,x_2)$ ; $(x_2,x_3)$ ; $(x_3,x_4)$ , and so on.

The ° symbol means "degrees." Any answer marked with that is definitely in degrees. The technically correct thing to do is to assume that everything is in radians unless otherwise specified.

Wouldn't it be 172≽1≽3 (I'm assuming ≽ means comes after) since 172 comes after 3 and 1? Or am I wrong, if you don't mind me asking. $\endgroup$ – user287997

2012年10月10日 · $\begingroup$ @Gyu Eun Lee That has the same equation, so maybe is why Jaden M. asked this question, but the question you linked looks like a homework problem that asks for the inverse of particular numbers and the derivative of the inverse at a particular number, but specifically avoids the much harder problem of finding an explicit formula for the inverse, which is what this question asks ...
