SUMMARY

The discussion centers on deriving an analytic formula for the cumulative distribution function (CDF) in relation to the probability density function (PDF). The CDF is defined as F(x) = ∫_{-∞}^x f(t) dt, where F'(x) = f(x). Additionally, the conversation touches on the properties of analytic functions, specifically proving that if f(z) is analytic, then its conjugate f*(z*) is also analytic. This highlights the relationship between analytic functions and their conjugates in complex analysis.

PREREQUISITES
  • Understanding of cumulative distribution functions (CDF) and probability density functions (PDF).
  • Knowledge of integral calculus, specifically integration techniques.
  • Familiarity with complex analysis, particularly the properties of analytic functions.
  • Basic concepts of function conjugation in complex variables.
NEXT STEPS
  • Study the properties of analytic functions in complex analysis.
  • Learn about the relationship between CDF and PDF in probability theory.
  • Explore integration techniques for deriving functions from their derivatives.
  • Investigate the implications of function conjugation in complex analysis.
USEFUL FOR

Students studying probability theory, mathematicians focusing on complex analysis, and anyone interested in the properties of analytic functions and their applications in statistics.

Derive an analytic forumula for a CDF

Homework Equations





The Attempt at a Solution



All I really want to know is what an analytic formula is? I know that the CDF is basically an integral of the PDF. I have looked all over the internet and can not find anything of the definition of an analytic formula.

Thanks!

Unless they have a specific CDF F(x) in mind, perhaps they just mean

F(x) = \int_{-\infty}^x f(t)\, dt \hbox{ so } F'(x) = f(x)

Edit Corrected typo.

Thanks. That's what I kinda figured, but I wanted to make sure that is what they ment.

Thanks again!
 
Hi can someone help me please? I am trying to do the following problem:
Prove that if f(z) is analytic, f*(z*) is also analytic. The stars represent conjugates. Thanks!
