Shape of t distribution

WebbMath Statistics Ch. 9 5.0 (1 review) When n is small (less than 30), how does the shape of the t distribution compare to the normal distribution? It is taller and narrower than the normal distribution. It is almost perfectly normal. It is flatter and more spread out than the normal distribution. WebbAnd here is how to do Bayesian t distribution fitting with brms::brm. First we simulate a sample of size n from t ( μ = 0, σ = 1, ν = 2.5) where μ is the location, σ is the scale and ν …
