Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! In probability theory and statistics, the variance of a random variable or distribution is the expected, or mean, value of the square of the deviation of that variable from its expected value or mean. Thus the variance is a measure of the amount of variation within the values of that variable, taking account of all possible values and their probabilities or weightings, not just the extremes which give the range. For example, a perfect die, when thrown, has expected value, expected absolute deviation the mean of the equally likely absolute deviationsbut expected square deviation or variance.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - High Quality Content by WIKIPEDIA articles! In probability theory and statistics, two real-valued random variables are said to be uncorrelated if their covariance is zero. Uncorrelatedness is by definition pairwise; i.e. to say that more than two random variables are uncorrelated simply means that any two of them are uncorrelated. Uncorrelated random variables have a correlation coefficient of zero, except in the trivial case when both variables have variance zero (are constants). In this case the correlation is undefined.…

Thus the variance is a measure of the amount of variation within the values of that variable, taking account of all possible values and their probabilities or weightings (not just the extremes which give the range). For example, a perfect dice, when thrown, has expected value (1+2+3+4+5+6)/6 = 3.5, expected absolute deviation 1.5 (the mean of the equally likely absolute deviations (3.5 1, 3.5 2, 3.5 3, 4 3.5, 5 3.5, 6 3.5), giving 2.5, 1.5, 0.5, 0.5, 1.5, 2.5, but expected square deviation or variance of 35/12 2.9 (the mean of the equally likely squared deviations 1/4, 9/4, and 25/4).…

In statisticsthe Chapman-Robbins bound or Hammersley- Chapman-Robbins bound is alower bound on the variance of estimators of a deterministic parameter.It is a generalization of the Cramér-Rao bound; compared to theCramér-Rao bound, it is both tighter and applicable to a wider range ofproblems. However, it is usually more difficult to compute.…

In probabilitytheory and statistics, kurtosis (from the Greek word ¿¿¿¿¿¿, kyrtos orkurtos, meaning bulging) is a measure of the 'peakedness' of theprobability distribution of a real-valued random variable. Higherkurtosis means more of the variance is the result of infrequent extremedeviations, as opposed to frequent modestly sized deviations.…
