tDist-class {tileHMM} | R Documentation |
This class provides objects representing scaled t distributions.
Objects can be created by calls of the form new("tDist", mean, var, df)
.
mean
:var
:df
:The distribution has density
f(x; mean, var, df) = gamma((df+1)/2)/{sqrt[var * pi * df (1 + (x - mean)^2 / (var * df))^(df + 1)] * gamma(df/2)}
components
:"matrix"
with columns weight
, mean
,
variance
, and df
. For objects of class "tDist"
this matrix has only one row
and weight
is always 1.
Class "contDist"
, directly.
Class "dist"
, by class "contDist", distance 2.
