The K-distribution is a probability distribution that occurs as the result of a statistical or probabilistic model used in Synthetic Aperture Radar (SAR) imagery. The K distribution is created by compounding two different probability distributions, where one representing the radar cross-section and the other one representing speckle that is a feature of coherent imaging.
This model is used to present the observed intensity X, includes compounding two gamma distributions. In all cases a reparameterisation of the common form of the family of gamma distributions is used, such that the parameters are as follows:
• the usual shape parameter and
• the mean of the distribution
The model is such that X has a gamma distribution with mean σ and shape parameter L, with σ treated as a random variable and having another gamma distribution, this time with mean μ and shape parameter ν. The outcome is that X has the following density function (x > 0):

here K is a modified Bessel function of the second kind. In this complete derivation, the K-distribution is a compound probability distribution and also a product distribution. Product distribution is the distribution of the product of two independent random variables, one having a gamma distribution with mean μ and shape parameter ν and the second having a gamma distribution with mean 1 and shape parameter L.
Jakeman and Pusey in 1978 derive this distribution on paper.
There are various other topics that are very much complicated and complex. Students find statistics assignment very difficult to understand. They require some help and guidance from outside. Online statistics assignment help is the best option available for them. Through this they can get assignments done with experts and also in given deadlines. Other than that they can take help from experts by sitting at their home through their PC and high speed internet connection only. So now statistics becomes easy for students.
