Specify truncation parameters for transportIP and transportTADA.
Usage
trunc(type = c("quantile", "raw"), value)
Arguments
- type
One of "quantile" or "raw". If "quantile", the truncation threshold is the quantile of the weights specified by value. If "raw", the truncation threshold is value.
- value
Value of threshold as described above. When type = "quantile", this argument should be between 0 and 1.
Value
A trunc object that can be processed by transportIP and transportTADA for weight truncation.
Details
Here, truncation refers to the procedure of setting weights above a threshold equal to the threshold. Thus, observations with extreme weights are included in the analysis, albeit with reduced weights.
