This study introduces a method for calculating confidence intervals for Poisson distribution differences using Bessel functions. These intervals are crucial for statistical analysis in various scientific fields.

Area of Science:

  • Statistics
  • Probability Theory
  • Applied Mathematics

Background:

  • Neyman-Pearson principles are fundamental in hypothesis testing.
  • Poisson distributions are commonly used to model count data.
  • Confidence intervals are essential for quantifying uncertainty in statistical estimates.

Purpose of the Study:

  • To present a method for calculating 95% confidence intervals for the difference between two Poisson distributed random variables.
  • To explore the application of modified Bessel functions in this statistical context.

Main Methods:

  • The study utilizes the relationship between the probability of the difference of two Poisson variables and modified Bessel functions of integral order.
  • Neyman-Pearson principles are referenced to frame the confidence interval construction.
