What are the properties of poisson distribution?
It is a discrete distribution in which the men and variance have the same value.
What properties distinguishes standard normal distribution from other normal distribution?
The normal distribution can have any real number as mean and any positive number as variance. The mean of the standard normal distribution is 0 and its variance is 1.
Are the mean and variance equal in the poisson distribution?
yes
Is in binomial distribution mean always greater then variance?
yes
1 The average of the squared deviation scores from a distribution mean?
Variance
How do you derive mode of Pareto Distribution?
The mode of the Pareto distribution is its lowest value.
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 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 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.
Which distribution function has equal mean and variance?
The exponential distribution and the Poisson distribution.
What is the variance for the uniform random variable?
the variance of the uniform distribution is (a+b)/12
Does a leptokurtic distribution have a larger variance than Mesokurtic distribution?
yes
What is the different between standard normal distribution and normal distribution?
A normal distribution can have any value for its mean and any positive value for its variance. A standard normal distribution has mean 0 and variance 1.
What is the variance of the uniform distribution function?
the variance of the uniform distribution function is 1/12(square of(b-a)) and the mean is 1/2(a+b).
What are the properties of poisson distribution?
It is a discrete distribution in which the men and variance have the same value.
What properties distinguishes standard normal distribution from other normal distribution?
The normal distribution can have any real number as mean and any positive number as variance. The mean of the standard normal distribution is 0 and its variance is 1.
