Probability t distribution
WebbThe probability density function for t is: f ( x, ν) = Γ ( ( ν + 1) / 2) π ν Γ ( ν / 2) ( 1 + x 2 / ν) − ( ν + 1) / 2. where x is a real number and the degrees of freedom parameter ν (denoted df … WebbCalculates the probability density function and lower and upper cumulative distribution functions of the student's t-distribution.
