check_kolmogorov_smirnov(w, c, ci_appr, counter_weight = NULL)

Arguments

• w: A vector of observed continuous exposure variable.
• c: A data.frame of observed covariates variable.
• ci_appr: The causal inference approach.
• counter_weight: A weight vector in different situations. If the matching approach is selected, it is an integer data.table of counters. In the case of the weighting approach, it is weight data.table.

Returns

output object is list including:

• ks_stat
• maximal_val
• mean_val
