Web23 de abr. de 2024 · If a normal distribution has mean μ and standard deviation σ, we may write the distribution as N ( μ, σ). The two distributions in Figure 3.1. 3 can be written as. (3.1.1) N ( μ = 0, σ = 0) and. (3.1.2) N ( μ = 19, σ = 4). Because the mean and standard deviation describe a normal distribution exactly, they are called the distribution's ... WebNormal and exp(2) distributions are crawling near 0 when x=5. Especially for normal distribution, its pdf value of 5 standard deviation is 0.000001486 (=pnorm(5)). This is around 8000 times smaller than that of Cauchy distribution. In other words, 5 sigma events are 8000 times more likely to happen under Cauchy distribution than Normal ...
