If x is gaussian normal μ σ y ax+ b is
Web19 jan. 2024 · Ok, so you recognize this as the equation of a normal distribution with mean = μ and standard deviation = σ. Comparing it to the general form of a Gaussian λ exp(-ax^2), we can see that: The term (x−μ)^2 is just how we employ the mean μ in a way that translates the graph left or right along the x axis, which is all we really want the mean to do.
