• statistical
• You can easily generate data from a normal distribution using any of the commonly available statistical packages. (uvm.edu)
• A log-normal process is the statistical realization of the multiplicative product of many independent random variables, each of which is positive. (wikipedia.org)
• subclass
• The NIG distribution was noted by Blaesild in 1977 as a subclass of the generalised hyperbolic distribution discovered by Ole Barndorff-Nielsen, in the next year Barndorff-Nielsen published the NIG in another paper. (wikipedia.org)
• given
• Approximations to this distribution that are easier to manipulate mathematically have been given by Ashour and Abdel-Hamid (2010) and by Mudholkar and Hutson (2000). (wikipedia.org)
• often
• As a consequence, when we have samples of hundreds of observations we can often ignore the distribution of the data. (bmj.com)
• approximate
• Well, the final position of each ball is determined by many (here only 8) independent, random events of whether to drop to the left or the right of the pin, thus the (approximate) normal distribution. (uky.edu)
• It is possible to fit the generalized normal distribution adopting an approximate maximum likelihood method. (wikipedia.org)
