If time series x is the similar to time series y then the variance of x-y should be less than the variance of x. We can test this using a one sided F test for variance. If the ratio var(x-y)/var(x) is significantly less than one then then y explains a significant proportion of the variance of x.

7 Ιαν 2016 · In the jargon of hypothesis testing, α is set to address the type-1 error rate, type-1 error being the incorrect rejection of the null hypothesis. The second variable you will be asked to fill in, is the β, or ‘1 – the power’ of the study to detect a true difference.
9 Ιαν 2019 · Given two (numeric) samples I would like to show that there is not a significant difference between the two means $\mu_{1}$ and $\mu_{2}$. If my goal was to show a significant difference I would formulate the $t$ -test as follows:
25 Σεπ 2013 · Similar to @Arjun Sol, instead of using Date.parse, you could just grab the times from the string itself, create a new Date object and do the comparison. const time1 = '12:42'; const time2 = '18:30'; const getTime = time => new Date(2019, 9, 2, time.substring(0, 2), time.substring(3, 5), 0, 0);
1 Ιαν 2012 · Each time you make a test there's a chance, at the level of alpha, that you make an error saying there's a real difference when there isn't one. By adjusting alpha down you make up for the fact that that chance is inflated across all of your tests, in your case 1-(1-alpha)^4, or 0.185.
1 Ιουν 2022 · Alpha-mu oscillations (8-12 Hz) of right parietal channels have been related to social coordination in several studies (Dumas et al., 2010; Naeem et al., 2012 a; Naeem et al., 2012 b; Tognoli et al., 2007).
