Random variable

A function that assigns a real number to each and every possible outcome of a random experiment.

Random Variable

In statistics, a variable expressing all possible outcomes of a set of circumstances. It is important in probability density function and probability distribution.

Although the patterns of canonical loadings on the perfectionism variates appear to support the distinction between maladaptive and adaptive profiles of perfectionism (see Lo & Abbott, 2013), it is the associations between the perfectionism variates and the social-loafing variates that are of particular interest.
Prior to testing our hypotheses, we examined relationships among the variables that compose each variate for multi-collinearity (defined as r > .90; Meyers, Gamst, & Guarino, 2006).
where variable [Z.sub.j] represents a weight for the probability of changes in each pixel to identify a greater chi-square value, [M.sub.kj] is the MAD variate of the kth band for pixel j, and [mathematical expression not reproducible]i is the variance of the no-change distribution.
(1995) and Stevens (2009) suggest the use of the correlation between individual observable variables and the associated canonical variates for interpretation.
After accounting for the relationships between statistics anxiety and motivational beliefs in the first canonical variates, the second pair of canonical variates indicates that all motivational beliefs components are still related to test anxiety, interpretation anxiety, and worth of statistics.
It can be seen from (5) that envelope and phase are independent variates. This is coherent with the complex Nakagami-m model [4, 5] in which the independence condition arose naturally out of the derivation of the model.

From the definition, it is clear that if [summation] = 0, then for Re(a) > (m-1)/2, the extended matrix variate gamma function reduces to the multivariate gamma function [[GAMMA].sub.m](a).
For [OMEGA] = [I.sub.m], the above density reduces to a standard matrix variate gamma density and in this case we write X ~ Ga(m, v, [theta]).
To determine if the observed variations differ between sexes, Canonical Variate Analysis (CVA) was conducted (Tables 4 and 5).
These structure correlations are calculated by multiplying the vector and canonical weights by the matrix of the within set of correlations for each variate according to the following equations:
As shown in Table 2, the first pair of canonical variates was positively correlated with the ADMS.
