Normal likelihood function

WebThe normal probability density function (pdf) is y = f ( x μ, σ) = 1 σ 2 π e − ( x − μ) 2 2 σ 2, for x ∈ ℝ. The likelihood function is the pdf viewed as a function of the parameters. The maximum likelihood estimates (MLEs) are the parameter estimates that maximize the likelihood function for fixed values of x. WebCorrections.
