dgamma(x, a, b=1) pgamma(x, a, b=1) qgamma(x, a, b=1) rgamma(x, a, b=1)
a and b.
dgamma gives the density,
pgamma gives the distribution function
qgamma gives the quantile function
and
rgamma generates random deviates.
The gamma distribution with parameters a and b
has density
Equations will come with HTML3
for x >= 0 ,
a > 0
and
b > 0 .
