What is the PDF of Gaussian distribution?

The PDF of the Gaussian random variable has two parameters, m and σ, which have the interpretation of the mean and standard deviation respectively. 1 The parameter σ2 is referred to as the variance. An example of a Gaussian PDF is shown in Figure 3.5.

Can Gaussian PDF be greater than 1?

The values of probability density function can be greater than one. The actual probability P(X<x) for random variable X with probability density function p(x) is integral ∫x−∞p(t)dt. The values of this integral are of course restricted to interval [0,1].

Does normal distribution have PDF?

The difference between a discrete random variable is that you can identify an exact value of the variable. The normal distribution is a common example of a PDF, forming the well-known bell curve shape.

Is normal distribution PDF or CDF?

We usually denote the standard normal CDF by Φ. The CDF of the standard normal distribution is denoted by the Φ function: Φ(x)=P(Z≤x)=1√2π∫x−∞exp−u22du. As we will see in a moment, the CDF of any normal random variable can be written in terms of the Φ function, so the Φ function is widely used in probability.
