A3.1 Normal Distribution
Recall from equation (1.1) that the probability density function is defined by
where μ and σ 2 are parameters that describe the curve. In this case, we write y ∼ N(μ, σ 2). Straightforward calculations show that
Thus, the notation y ∼ N(μ, σ 2) is interpreted to mean that the random variable ...
