WebFor a bimodal or skewed distribution, the sample mean would not be a good approximation of the MAP estimate. Let's consider a bimodal distribution, which can be represented as a mixture of two Gaussian distributions with different means µ1 and µ2: P r (θ ∣ V) = p ⋅ G (θ, μ 1 , σ 1 ) + (1 − p) ⋅ G (θ, μ 2 , σ 2 ) WebA unimodal distribution only has one peak in the distribution, a bimodal distribution has two peaks, and a multimodal distribution has three or more peaks. Another way to describe the shape of histograms is by describing whether the data is skewed or symmetric.
