As you might already know, India has more than 50% of its population below the age of 25 and more than 65% below the age of 35. If you plot the distribution of the age of the population of India, you will find that there is a hump on the left side of the distribution, and the...
In the statistical distribution of heavy metals, As, Cr and Cu are slightly right-skewed, with skewness indexes less than 1 and peak indexes (kurtosis) that is not high. However, the content distributions of Cd and Hg are seriously right-skewed, with skew indexes of 3.99 and 4.61, and co...
Purpose - This paper aims to present the results of further investigating the Polimenis (2012) stochastic model, which aims to decompose the stock return evolution into positive and negative jumps, and a Brownian noise (white noise), by taking into account different noise levels. This paper ...
KS test checks if two independent distributions are similar or different, by generating cumulative probability plots for two distributions and finding the distance along the y-axis for a given x values between the two curves. From all the distances calculated for each x value, the maximum distance...
Due to the non-existence of closed-form expression for the cor- responding densities, standard procedures for estima- tion of the parameters of positive stable distributions appear to be computationally expensive. In this note we show that the first two moments of negative order provide a ...
Because of these properties, there is an increasing interest to derive bimodal distributions in the literature: refs. [5,6] presented extensions of the skew-normal, ref. [7] proposed a generalization of the Burr type X distribution and [8] derived an extension of the sinh Cauchy distribution...

, but all exhibit two symmetries in the joint distribution 𝑝(𝑥1,𝑥2)p(x1,x2) that are required in the absence of prior information: exchangeability of variables, and non-informative priors over the marginal distributions 𝑝(𝑥1)p(x1) and 𝑝(𝑥2)p(x2). We relate our ...
