With a three state model, we might say that the emissions are Gaussian distributed, but the location ( μ) and scale ( σ) vary based on which state we are in. In the simplest case: State 1 gives us data y1 ∼ N(μ = 1, σ = 0.2) State 2 gives us data y2 ∼ N(μ = 0, σ = 0.5) list of toyota suvs by size https://heppnermarketing.com
