Example 2. Suppose that there are two red balls and three white balls in a bag, catch one ball from the bag twice without put back, and define X and Y as follows: ball white is put second the 0 ball red is put

Example. Consider an experiment that consists of tossing a die and a coin at the same time. We can consider a number of random variables defined on this sample space. We will assign an indicator random variable to the result of tossing the coin. If it comes up heads we will assign a ...
In the one-dimensional case,Sigmais the variance, not the standard deviation. For example,mvnrnd(0,4)is the same asnormrnd(0,2), where4is the variance and2is the standard deviation. References [1] Kotz, S., N. Balakrishnan, and N. L. Johnson.Continuous Multivariate Distributions: Volume...
“Multivariate data are data for which each observation consists of values for more than one random variable on each experimental unit” (Fisher and van Belle, 1993). As an example, consider a study, described by Everitt and Hay (1992), to determine whether postpartum depression is associated...
For example, in the basic univariate SV model, we include the T latent volatilities in the parameter space, with T being the sample size. As these volatilities are dependent, they cannot be counted as T additional free parameters. Consequently, AIC is not applicable for Multivariate Stochastic ...
Random samples consistently yielded around 9–11 optimal clusters, with one example (10 clusters) shown in this panel. A Jaccard similarity of 0.25 corresponds to two subsets having 4 out of 10 nodes in common. b Frequency of individual node participation across 100,000 synergistic subsets, ...

You can design your research so that causal factors are made independent of each other.For example, if you think that there may be a link between age and salary, then a random sample of employees will risk combining the effects of both. If, however, you divide the population into groups ...
The cluster number assigned to a set of features may change from one run to the next. For example, if you partition features into two clusters based on an income variable, the first time you run the analysis you might see the high income features labeled as cluster 2 and the low income...
