 `rsofun` supports both optimization using the `GenSA` and `BayesianTools` packages. The above statement provides settings for a `GenSA` optimization approach. For this example the maximum number of iterations is kept artificially low. In a real scenario you will have to increase this value orders of magnitude. Keep in mind that optimization routines rely on a cost function, which, depending on its structure influences parameter selection. A limited set of cost functions is provided but the model structure is transparent and custom cost functions can be easily written. More details can be found in the "Parameter calibration and cost functions" vignette.

Free parameters include: parameters for the quantum yield efficiency `kphio`, `kphio_par_a` and `kphio_par_b`, soil moisture stress parameters `soilm_thetastar` and `soilm_betao`, and also `beta_unitcostratio`, `rd_to_vcmax`, `tau_acclim` and `kc_jmax` (see `?runread_pmodel_f`). Be mindful that with newer versions of `rsofun` additional parameters might be introduced, so re-check vignettes and function documentation when updating existing code.

 With all settings defined the optimization function `calib_sofun()` can be called with driver data and observations specified. Extra arguments for the cost function (like what variable should be used as target to compute the root mean squared error (RMSE) and previous values for the parameters that aren't calibrated, which are needed to run the P-model).

+#' Cost function computing a log-likelihood for calibration of Phydro-model
+#' parameters
+#' 
+#' The cost function performs a Phydro-model run for the input drivers and model parameter
+#' values, and computes the outcome's normal log-likelihood centered at the input
+#' observed values and with standard deviation given as an input parameter 
+#' (calibratable).
+#' 
+#' @param par A vector of values for the parameters to be calibrated, including
+#' a subset of model parameters (described in \code{\link{runread_pmodel_f}}),
+#' in order, and error terms
+#' for each target variable (for example \code{'gpp_err'}), in the same order as
+#' the targets appear in \code{targets}.
+#' @param obs A nested data.frame of observations, with columns \code{'sitename'}
+#' and \code{'data'} (see \code{\link{p_model_validation}} or \code{\link{p_model_validation_vcmax25}}
+#' to check their structure). 
+#' @param drivers A nested data.frame of driver data. See \code{\link{p_model_drivers}}
+#' for a description of the data structure.
+#' @param targets A character vector indicating the target variables for which the
+#' optimization will be done and the RMSE computed. This string must be a column 
+#' name of the \code{data} data.frame belonging to the validation nested data.frame 
+#' (for example 'gpp').
+#' @param par_fixed A named list of model parameter values to keep fixed during the
+#' calibration. These should complement the input \code{par} such that all model
+#' parameters are passed on to \code{\link{runread_pmodel_f}}.
+#' @param parallel A logical specifying whether simulations are to be parallelised
+#' (sending data from a certain number of sites to each core). Defaults to
+#' \code{FALSE}.
+#' @param ncores An integer specifying the number of cores used for parallel
+#' computing. Defaults to 2.
+#' 
+#' @return The log-likelihood of the observed target values, assuming that they
+#' are independent, normally distributed and centered on the predictions
+#' made by the P-model run with standard deviation given as input (via `par` because
+#' the error terms are estimated through the calibration with `BayesianTools`,
+#' as shown in the "Parameter calibration and cost functions" vignette).
+#' 
+#' @details To run the P-model, all model parameters must be given. The cost
+#' function uses arguments \code{par} and \code{par_fixed} such that, in the
+#' calibration routine, \code{par} can be updated by the optimizer and 
+#' \code{par_fixed} are kept unchanged throughout calibration.
+#' 
+#' If the validation data contains a "date" column (fluxes), the simulated target time series
+#' is compared to the observed values on those same dates (e.g. for GPP). Otherwise, 
+#' there should only be one observed value per site (leaf traits), and the outputs 
+#' (averaged over the growing season, weighted by predicted GPP) will be 
+#' compared to this single value representative of the site (e.g. Vcmax25). As an exception,
+#' when the date of a trait measurement is available, it will be compared to the 
+#' trait value predicted on that date.

+\arguments{
+\item{par}{A vector of values for the parameters to be calibrated, including
+a subset of model parameters (described in \code{\link{runread_pmodel_f}}),
+in order, and error terms
+for each target variable (for example \code{'gpp_err'}), in the same order as
+the targets appear in \code{targets}.}
+
+\item{obs}{A nested data.frame of observations, with columns \code{'sitename'}
+and \code{'data'} (see \code{\link{p_model_validation}} or \code{\link{p_model_validation_vcmax25}}
+to check their structure).}
+
+\item{drivers}{A nested data.frame of driver data. See \code{\link{p_model_drivers}}
+for a description of the data structure.}
+
+\item{targets}{A character vector indicating the target variables for which the
+optimization will be done and the RMSE computed. This string must be a column 
+name of the \code{data} data.frame belonging to the validation nested data.frame 
+(for example 'gpp').}
+
+\item{par_fixed}{A named list of model parameter values to keep fixed during the
+calibration. These should complement the input \code{par} such that all model
+parameters are passed on to \code{\link{runread_pmodel_f}}.}
+
+\item{parallel}{A logical specifying whether simulations are to be parallelised
+(sending data from a certain number of sites to each core). Defaults to
+\code{FALSE}.}
+
+\item{ncores}{An integer specifying the number of cores used for parallel
+computing. Defaults to 2.}
+}
+\value{
+The log-likelihood of the observed target values, assuming that they
+are independent, normally distributed and centered on the predictions
+made by the P-model run with standard deviation given as input (via `par` because
+the error terms are estimated through the calibration with `BayesianTools`,
+as shown in the "Parameter calibration and cost functions" vignette).
+}
+\description{
+The cost function performs a Phydro-model run for the input drivers and model parameter
+values, and computes the outcome's normal log-likelihood centered at the input
+observed values and with standard deviation given as an input parameter 
+(calibratable).
+}
+\details{
+To run the P-model, all model parameters must be given. The cost
+function uses arguments \code{par} and \code{par_fixed} such that, in the
+calibration routine, \code{par} can be updated by the optimizer and 
+\code{par_fixed} are kept unchanged throughout calibration.
+
+If the validation data contains a "date" column (fluxes), the simulated target time series
+is compared to the observed values on those same dates (e.g. for GPP). Otherwise, 
+there should only be one observed value per site (leaf traits), and the outputs 
+(averaged over the growing season, weighted by predicted GPP) will be 
+compared to this single value representative of the site (e.g. Vcmax25). As an exception,
+when the date of a trait measurement is available, it will be compared to the 
+trait value predicted on that date.

Subject: [PATCH 06/15] Fix test-calibration-pmodel.R: add 'whc' and switch
 prior to uniform

Previously prior was changed to a TruncatedNormal, this then requires additional specifications of mean and sd for each parameter prior. For the tests it is easier to switch to a uniform prior.
