An S4 class container for the result of the function
matrix with as many rows as inputs and three columns. Values of the PLS-PCE sensitivity indexes. The column labels are LE, PE, TPE.
indexes[i, "LE"] is the Linear Effect of the input
indexes[i, "PE"] is the Polynomial Effect. It is the effect of the
monomials in which only the input
indexes[i, "TPE"] is the Total Polynomial Effect. It is the effect of all the
monomials in which the input
Percentages of the PLS-PCE sensitivity indexes, i.e
indexes expressed as percentages
of the sums of their columns.
number of the optimal component.
matrix with as many rows as components and three columns. The columns are labeled R2, %R2 and %R2cum. They store respectively the R2 values, percentages of their column sums, and cumulated values of their percentages.
matrix with as many rows as components and two columns. The columns are labeled Q2 and Q2cum. They store respectively the Q2 and the Q2cum values.
matrix with as many rows as components and one column. Root mean square error predictions.
matrix with as many rows as monomials plus one and as many columns as components. PLS-regression coefficients. The first row is the constant term.
matrix with as many rows as monomials and as many columns as components. The centered-reducted PLS-regression coefficients, for all the components.
vector of length equal to the number of rows of the dataset. Metamodel outputs.
object of class
PCEdesign coding the polynomial structure.
signature(x = "PLSPCE", all=FALSE, ...):
method of function
all is FALSE, some
slots are hidden :
RMSEP, coef, betaCR, y.hat, STRUC.
all is set to TRUE,
the names of the hidden slots are printed. The additional arguments are passed to the
signature(object = "PLSPCE"): same as
signature(x = "PLSPCE", pce, options =c("fit", "bar", "compo")):
method of function
Different plots are drawn, according to
When it includes “fit”,
computer model outputs against metamodel outputs.
When it includes “bar”,
barplots of the polynomial
and total polynomial effects (PE and TPE).
When it includes “compo”,
TPE against components. This last plot requires the
calculation of the TPE for each component, which may take some time.
STRUC slots can be used for making
for Legendre-coded new input values.
