anam-class {RGeoS} | R Documentation |
This Class contains the anamorphosis which describes the way samples can be transformed from raw (Y) to gaussian (Z) scale, and vice-versa
Objects can be created by calls of the form new("anam", ...)
.
The anamorphosis function enables the user to turn from raw to gaussian (and vice versa).
nh
:Object of class "numeric"

pymin
:Object of class "numeric"
Minimum practical value for Y
pzmin
:Object of class "numeric"
Minimum practical value for Z
pymax
:Object of class "numeric"

pzmax
:Object of class "numeric"

azmin
:Object of class "numeric"
Minimum absolute value for Z
aymax
:Object of class "numeric"
Maximum absolute value for Y
azmax

psi
:Object of class "numeric"
Coefficients of the Hermite polynomials
anam[i]<-value
assigns value
to the coefficient of the i-th
Hermite polynomial of the anam
Class.
anam[i]
returns the coefficient of the i-th
Hermite polynomial of the anam
Class.
anam$parameter
is used to query the value of parameter
from anam
:
nh : Number of Hermite polynomials
pymin : Minimum practical value for Y
pymax : Maximum practical value for Y
pzmin : Minimum practical value for Z
pzmax : Maximum practical value for Z
aymin : Minimum absolute value for Y
aymax : Maximum absolute value for Y
azmin : Minimum absolute value for Z
azmax : Maximum absolute value for Z
variance : Variance of the variable
psi : Array of Hermite coefficients
Same as the previous method but for assignment
Other functions are available, such as:
anam.fit
Fit the gaussian anamorphosis from a variablein a db-class
to create a anam-class
anam.y2z
Transform a Gaussian variable into a Raw variable
anam.z2y
Transform a Raw variable into a Gaussian variable
