MCA maximises the temporal covariance between two different data fields and is closely related to Principal Component Analysis (PCA) / Empirical Orthogonal Function analysis (EOF analysis). While EOF analysis maximises the variance within a single data field, MCA allows to extract the dominant co-...

This is due to the fact that correlation coefficient is a function of covariance. Statistical concepts form the foundation of many data analytics and data science techniques. To try your hand at some simple data analysis with a real dataset, give CareerFoundry’s free five-day data short course...
Let XX and YY be as in Example 5.24 in Section 5.2.3, i.e., suppose that we choose a point (X,Y)(X,Y) uniformly at random in the unit disc D={(x,y)|x2+y2≤1}.D={(x,y)|x2+y2≤1}. Are XX and YY uncorrelated?
Here , the correlation results on original dаta is similar to covariance on standardized dаta ( with deviation in decimal values ) . For any of our applications like PCA , we can use either of them which yields the same results. Alternatively, we can use function from NumPy modules as...

For general cognitive function as measured by MMSE at baseline, while sNC participants from BABRI presented better cognition than pNC (p < 0.001), the pNC showed quite similar cognition with sNC in ADNI (p = 0.213). rMCI in both samples were cognitively better than non-rMCI (p = 0.066 in...
