Description Usage Arguments Value Note Examples

The validation is based on different types of statistics computed on WACS data, WACS parameters and WACS simulations.

`what` |
Type of validation. Possible choices are:
| |||||||||||||||

`wacsdata` |
WACS data obtained when calling WACSdata | |||||||||||||||

`wacspar` |
WACS parameters estimated when calling WACSestim | |||||||||||||||

`wacssimul` |
WACS simulation obtained when calling WACSsimul | |||||||||||||||

`varname` |
Variable on which the validation is performed | |||||||||||||||

`varname2` |
Second variable on which validation is performed (only needed if | |||||||||||||||

`base` |
Threshold used for "SumBase" and "Persistence" | |||||||||||||||

`above` |
Boolean value used for "Persistence": TRUE if data is considered above threshold; FALSE otherwise | |||||||||||||||

`months` |
Months to which the analysis should be restricted (only for "SumBase" and "Persistence") |

A list containing all information needed for plots; contains also the type of validation, as a class

If `what=sim`

, data and simulations are displayed as a function of the day of the year, from 1 to 365.
Smoothed versions of daily average and daily envelopes (defined by average +/- 2. standard deviations) are also displayed.

If `what=rain`

, qq-plots and superimposition of histograms and models of rain are produced for each season.

If `what=MeanSd`

, boxplots of monthly means and monthly standard deviations are compared.
The median value of the monthly mean, resp. monthly standard deviation, of the data are displayed
on top of the boxplots computed on the simulations.

#' If `what=BiVar`

, boxplots of monthly correlations coefficients between `varname`

and `varname2`

are compared. The median value of the correlation coefficient computed on the data is displayed
on top of the boxplots computed on the simulations.

If `what=CorTemp`

, boxplots of monthly 1-day auto correlation are compared. The median value of the
auto-correlation coefficient computed on the data is displayed
on top of the boxplots computed on the simulations.

If `what=SumBase`

, boxplots of the sum of the variable `varname`

above a given threshold, `base`

,
is computed during the months provided in the variable `months`

.

If `what=Persistence`

, histograms of consecutive days of the variable `varname`

above (or below) a given
threshold, `base`

, are compared. If `above=TRUE`

, consecutive days above the threshold are computed,
whereas days below the threshold are computed if `above=FALSE`

. Months can be selected
with the variable `months`

.
