Moreover, the standardized covariance (i.e., the correlation) between the latent intercept and the latent slope of pornography use frequency was also negative for both men and women (see Table 3), indicating that individuals who reported greater use at baseline decreased their pornography use at...
dx,y=1−rx,y=1−covn(x,y)σxσy where r is the sample Pearson product-moment correlation coefficient, cov(x,y) is the sample covariance, and σ corresponds to the sample standard deviation. As r resides on the interval [-1,1], d resides on the interval [0,2].Installation...

In this work, we adopted a mixed-effects model [20] in estimating the co-expression effects between pairs of genes while allowing sample-level variation as random effects, with the covariance matrix of the random effects being proportional to sample-sample covariance of isoform composition. The mo...
Generally, the results from a factor analysis of a correlation matrix and the corresponding covariance matrix are not identical. When analyzing a covariance matrix, variables having large variance will influence the results of the analysis more than will variables having small variance. Because the var...

Problematic pornography use (PPU) is the inability to control the use of pornography and is considered a form of compulsive sexual behavior. It can have a
As seen in Section 2, random projection methods show good promise in mean vector testing. Using random projections for covariance matrices is an interesting question that is an active area of research. If R∈Rk×p is an orthogonal random matrix, then projecting the data using R preserves the ...
