You must know calculus, at least that the integral of xN = 1/(N+1)xN+1 . Define the Pareto distribution as: f(x) = abax-(a+1) or Cx-(a+1) where C = aba (a constant) Remember that the pdf is defined over the domain [b, inf] otherwise zero. Mean = integral xf(x) evaluated from b to infinity. Remember also that the limit of 1/x as x goes to infinity = 0. Similarly for any positive a, (1/x)a goes to 0 as x goes to infinity. mean = integral C x-(a+1)x dx = integral Cx-a = C(1/(-a+1))x-a+1 evaluated over the interval b to infinity. The integral is zero at infinity, so the mean = C(0-1/(-a+1))b-a+1 Remember b-a+1 = b-ab After substituting and cancelling mean = ab/(a-1) for a greater than 1.

How do you derive mean deviation from mean for pareto distribution?
The total deviation from the mean for ANY distribution is always zero.
What is the difference between a histogram and a pareto chart?
Both graphs are used to summarize data. Pareto chart is used to establish differences between different groups of data and will assign relative importance to the different groups of data. Histogram is a data distribution graph that will determine if the particular set of data is symmetric or not.
Why is the sample standard deviation used to derive the standard error of the mean?
the sample mean is used to derive the significance level.
The mean of a distribution of scores is the?
The mean of a distribution of scores is the average.
The mean of the distribution is 2.89 with a standard?
The mean of a distribution gives no information about the standard deviation.
How do you derive the mean of generalised pareto distribution?
To derive the mean of generalized Pareto distribution you must be good with numbers. You must be good in Calculus, Algebra and Statistics.
How do you derive mode of Pareto Distribution?
The mode of the Pareto distribution is its lowest value.
How do you derive mean deviation from mean for pareto distribution?
The total deviation from the mean for ANY distribution is always zero.
How do you derive the mean deviation about the mean of the pareto type 1 distributions?
Easy. The mean deviation about the mean, for any distribution, MUST be 0.
How do you derive variance of Pareto distribution?
var(X) = (xm/a - 1)2 a/a-2 . If a < or equal to 2, the variance does not exist.
How do you derive Moment generating function of Pareto distribution?
The moment generating function for any real valued probability distribution is the expected value of e^tX provided that the expectation exists.For the Type I Pareto distribution with tail index a, this isa*[-x(m)t)^a*Gamma[-a, -x(m)t)] for t < 0, where x(m) is the scale parameter and represents the least possible positive value of X.

What has the author Divakar Sharma written?
Divakar Sharma has written: 'On some estimators of the parameters of the Pareto distribution'
What do you mean by gaussian?
The Gaussian distribution is the same as the normal distribution. Sometimes, "Gaussian" is used as in "Gaussian noise" and "Gaussian process." See related links, Interesting that Gauss did not first derive this distribution. That honor goes to de Moivre in 1773.
How do you derive the rayleigh distribution?

When did Graziella Pareto die?
Graziella Pareto died in 1973.
When was Graziella Pareto born?
Graziella Pareto was born in 1889.
