The limit of a function is a fundamental concept in Calculus, defining the behavior of a function as the input approaches a specific value. The limit allows mathematicians to analyze functions near ...

ABSTRACT: In order to introduce left and right truncated versions of the modified lognormal with a power-law distribution, we derive its probability density function, its distribution function, its ...

ABSTRACT: Analytical functions which fit the probability distributions of stars and galaxies can provide insight into how these distributions originate. In order to introduce a truncated version of ...
