Con_Sampling_2D_Lag: Conditionally sampling a two dimensional dataset
In rjaneUCF/MultiHazard-R-Package: Tools for modeling compound events

Description Usage Arguments Value Examples

Creates a data frame where the declustered excesses of a (conditioning) variable are paired with the maximum value of a second variable over a specified lag.

1 2	Con_Sampling_2D_Lag(Data_Detrend, Data_Declust, Con_Variable, Thres = 0.97, Lag_Backward = 0, Lag_Forward = 0)

`Data_Detrend`	Data frame containing two at least partially concurrent time series, detrended if necessary. Time steps must be equally spaced, with missing values assigned `NA`. First object may be a `"Date"` object. Can be `Dataframe_Combine` output.
`Data_Declust`	Data frame containing two (independently) declustered at least partially concurrent time series. Time steps must be equally spaced, with missing values assigned `NA`. Columns must be in the same order as in `Data_Detrend`. First object may be a `"Date"` object. Can be `Dataframe_Combine` output.
`Con_Variable`	Column number (1 or 2) or the column name of the conditioning variable. Default is `1`.
`Thres`	Threshold, as a quantile of the observations of the conditioning variable. Default is `0.97`.
`Lag_Backward`	Positieve lag applied to variable not assigned as the `Con_Variable`. Default is `0`
`Lag_Forward`	Negative lag to variable not assigned as the `Con_Variable`. Default is `0`

List comprising the specifyied Threshold as the quantile of the conditioning variable above which declustered excesses are paired with co-occurences of the other variable, the resulting two-dimensional sample data and name of the conditioning variable.
