Question

What is the characteristic function of set? Explain it with a short note; elaborate it with not less than 3 examples.

Answer 1

Answer:

The characteristic function of any real-valued random variable completely defines its probability distribution. If a random variable admits a probability density function, then the characteristic function is the Fourier transform of the probability density function. Thus it provides an alternative route to analytical results compared with working directly with probability density functions or cumulative distribution functions
