\description{

Creation of the \code{InputsCrit} object required to the \code{\link{ErrorCrit}} function. This function defines a composite criterion based on the formula proposed by Lavenne et al. (2019).

\item{InputsModel}{[object of class \emph{InputsModel}] see \code{\link{CreateInputsModel}} for details}
35
36 
\item{RunOptions}{[object of class \emph{RunOptions}] see \code{\link{CreateRunOptions}} for details}
37
38 
\item{Obs}{[numeric (atomic or list)] series of observed variable ([mm/time step] for discharge or SWE, [-] for SCA)}
39
40 
\item{VarObs}{(optional) [character (atomic or list)] names of the observed variable (\code{"Q"} by default, or one of \code{"SCA"}, \code{"SWE"})}
41
42 
\item{AprParamR}{[numeric] a priori parameter set from a donor catchment}
43
44 
\item{AprCrit}{(optional) [numeric] performance criterion of the donor catchment (1 by default)}
45
46 
\item{k}{(optional) [numeric] coefficient used for the weighted average between \code{FUN_CRIT} and the gap between the optimised parameter set and an a priori parameter set calculated with the function produced by \code{\link{CreateErrorCrit_GAPX}}}
47
48 
\item{BoolCrit}{(optional) [boolean] boolean (the same length as \code{Obs}) giving the time steps to consider in the computation (all time steps are considered by default. See details)}
49
50 
\item{transfo}{(optional) [character] name of the transformation applied to the variables (e.g. \code{""}, \code{"sqrt"}, \code{"log"}, \code{"inv"}, \code{"sort"}, \code{"boxcox"} or a numeric value for power transformation for \code{FUN_CRIT}. Default value is \code{"sqrt"}. See details of \code{\link{CreateInputsCrit}}}
51
52 
\item{epsilon}{(optional) [numeric] small value to add to all observations and simulations for \code{FUN_CRIT} when \code{"log"} or \code{"inv"} transformations are used [same unit as \code{Obs}]. See details of \code{\link{CreateInputsCrit}}}
53

\value{
57
58 
[list] object of class InputsCrit containing the data required to evaluate the model outputs (see \code{\link{CreateInputsCrit}} for more details).
59
60 
\code{CreateInputsCrit_Lavenne} returns an object of class \emph{Compo}.
61
62 
Items \code{Weights} of the criteria are respectively equal to \code{k} and \code{k * max(0, AprCrit)}.
63
64 
To calculate the Lavenne criterion, it is necessary to use the \code{ErrorCrit} function as for any other composite criterion.

The parameters \code{FUN_CRIT}, \code{Obs}, \code{VarObs}, \code{BoolCrit}, \code{transfo}, and \code{epsilon} must be used as they would be used for \code{\link{CreateInputsCrit}} in the case of a single criterion.

\code{\link{ErrorCrit_RMSE}} cannot be used in a composite criterion since it is not a unitless value. \code{CreateInputsCrit_Lavenne} creates a composite criterion in respect with Equations 1 and 2 of de Lavenne et al.
