Description Usage Arguments Note Examples
Density, distribution function, quantile function and random generation for the generalised t distribution with a degrees of freedom, mean b and scale c

x |
vector of quantities |
p |
vector of probabilities |
n |
number of observations |
a |
degrees of freedom. Must be strictly positive. |
b |
mean |
c |
scale. Must be strictly positive. |
If X~t_a(b,c) then it has density f(x)=(1_(x-b)^2/(ac))^(-(a+1)/2)/(sqrt(ac)*Beta(a,b)). Also (X-b)/sqrt(c)~t_a.
