indicator |
Name of the indicator to be calculated. Possible values are "CumulativeCover", "PropOpportunist", and "NPerennials" |
df |
A dataframe with monitoring data for macroalgae according to the Danish National Marine Monitoring Program. The dataframe should contain the following variables:
|
boundaries |
A vector of length 4 giving the status class boundary values of the standardized indicator. The boundary values should be given in the order high-good, good-moderate, moderate-poor, poor-bad. |
depth_cutoff |
The cut-off depth for physical exposure. Observations whith depths shallower than this value are not used in the indicator calculation. |
std_depth |
The depth for which the indication is calculated. Default is 7 meters. |
std_haardsub |
The suitable substrate percentage for which the indicator if calculated. Default it 0.5. |
n_iter |
Maximum number of iteration for Montecarlo simulation. |
Indicator_pred_pct |
Probability for predicting the percentile in the simulated distribution. Default is 0.5 for the median. |
