Suppose that p(x|i,, i) N(i,), where is a common covariance matrix for all c classes.

Suppose that p(x|μi,Σ, ωi) ∼ N(μi,Σ), where Σ is a common covariance matrix for all c classes. Let n samples x1, ..., xn be drawn as usual, and let l1, ..., ln be their labels, so that lk = i if the state of nature for xk was ωi.
