inv.rho.transform {GMCM} | R Documentation |
Transformation of the correlation to real line and its inverse
Description
A transformation of the correlation coefficient into the real line and the
corresponding inverse. The transform is a translation and scaling of
\rho
from the interval (-1/(d-1), 1)
to
(0, 1)
followed by a logit transformation to the whole real
line.
Usage
inv.rho.transform(a, d)
rho.transform(rho, d)
Arguments
a |
A real number. |
d |
The dimension of the space. |
rho |
A correlation coefficient between |
Value
inv.rho.transform
returns a vector of the inversely
transformed values with the same length as a
.
rho.transform
returns a vector of the transformed values with
the same length as rho
or a
.
