Shape of t distribution
WebbThe Student probability density function f in [2] with n ∈ ( 0, ∞) degrees of freedom has the following properties: f is symmetric about t = 0. f is increasing and then decreasing with mode t = 0. f is concave upward, then downward, then upward again with inflection points at ± n / ( n + 1). f ( t) → 0 as t → ∞ and as t → − ∞.
