{
##INPUTS
## formula : ANOVA formula like "A+B+c+A:B" OR The max interaction
## order like 2 for example.
## model : Data.frame output matrix OR The name of the R-function
## which decribes the model. This function
## must take only a vector corresponding to the input factors values
## factors : Data.frame design if model is data.frame OR a list of factors
## levels: factor<- list(A=c(0,1),B=c(0,1,4))
## inertia : Inertia proportion account by Principal components <1 (0.95 default )
## OR number of PCs to be used (E.g 3)
## normalized : logical value. TRUE (default) computes a normalized Principal
## Component analysis.
## cumul : logical value. If TRUE the PCA will be done on the cumulative outputs
## simulonly : logical value. If TRUE the program simulates only the model outputs
## and stops
## Name.File : Name of file containing the R-function model.
## E.g "exc.ssc"
## ... : possible fixed parameters of the model function
## OUTPUTS
##GSI objet de classe gsi contient
##
## X : data.frame design of experiment (input sample)
## Y : data.frame output matrix (response)
## H :
## L :
## lambda :
## inertia : vector of inertia per PCs and Global criterion
## cor : data.frame of correlation between PCs and outputs
## SI : data.frame of first, two ... order Sensitivity Indices (SI) on PCs and
## first, two... order Generalised SI (GSI)
## mSI : data.frame of principal SI on PCs and principal GSI
## tSI : data.frame of total SI on PCs and total GSI
## iSI : data.frame of interaction SI on PCs and interaction GSI
## pred :
## residuals :
## Rsquare : vector of dynamic coefficient of determination
## Att : matrice 0-1 de correspondance facteurs*termes-du-modele
## normalized : logical value used for normalized
## cumul : logical value used for cumul
