11.2: The Density Curve of a Normal Distribution

WebProbability Density Function The general formula for the probability density function of the normal distribution is \( f(x) = \frac{e^{-(x - \mu)^{2}/(2\sigma^{2}) }} {\sigma\sqrt{2\pi}} \) where μ is the location parameter and σ is the scale parameter.The case where μ = 0 and σ = 1 is called the standard normal distribution.The equation for the standard normal … WebFigure 1: Solid red curve is a Cauchy density function with z 0=10 and b=1. The dashed curve is a Gaussian with the same peak as the Gaussian (1/π) with mean=10 and variance = π/2. The Cauchy has heavier tails. The terminology uses the band z 0parameters to define the Cauchy density function: photo sign in book
