We're interested in looking at diversified firms as well.Is this downturn worldwide, or are there variances by geography?You can't standardise a global downturn by region.
This can be used to show that, if X1,…, Xn are independent random variables, the variance of the sum X1 +⋯+ Xn is just the sum of the individual variances, Var X1) +⋯+ Var Xn).
For example, if (s1, t1) and (s2, t2) are disjoint intervals, the increments B t1) − B s1) and B t2) − B s2) are independent random variables that are normally distributed with expectation 0 and variances equal to σ2 t1 − s1) and σ2 t2 − s2), respectively.
In addition to the population mean, hypothesis-testing procedures are available for population parameters such as proportions, variances, standard deviations, and medians.
The formulas for computing the variances of discrete and continuous random variables are given by equations 4 and 5, respectively.
In 1961 the zoning code was altered to encourage developers to add public amenities to their building plans in return for variances.
Alterations of motor memory are identified by changes in means, variances, and correlations between test results.
This shows the profit that was planned for this period, the actual results received for this period, and the differences, or variances, between the two.
Statistical indices of psychomotor ability (e.g., means, variances, and correlations) not only differ among individuals but may also serve to distinguish from each other groups of persons classified by such traits as age, sex, personality, and intelligence.
Further artistic variances can be attributed to cultural time lag, for comparable stages of artistic development were not reached simultaneously throughout the area.
