tdistribution {lestat} | R Documentation |
Create an object representing a univariate non-centered t-distribution.
tdistribution(expectation = 0, degreesoffreedom = 1e+20,
lambda, P = 1)
expectation |
The expectation of the distribution. |
degreesoffreedom |
The degrees of freedom parameter. |
lambda |
The natural logarithm of the scale |
P |
An alternative to specifying the logged scale |
The probability density of a t-distribution with expectation \mu
,
degrees of freedom \nu
, and logged scale \lambda
is proportional to
f(x)=(\nu + e^{-2\lambda}(x-\mu)^2)^{-(\nu+1)/2}
A t-distribution.
