case class Normal(mu: Double = 0.0, sigma2: Double = 1.0, stream: Int = 0) extends Variate with Product with Serializable
This class generates Normal (Gaussian) random variates.
This continuous RV models normally distributed data (bell curve).
When summed, most distributions tend to Normal (Central Limit Theorem).
- mu
the mean
- sigma2
the variance (sigma squared)
- stream
