capWeight: Apply an exponent function if value beyond max threshold

In mbannert/gateveys: An R Toolbox for Business Tendency Survey Researchers

Description

This function adjusts the size of values in a numeric vector once value go beyond a certain threshold. The adjustment is done by an exponential function with the default exponent 0.7. In the context of business tendency surveys this function is often used to lower the influence of very large companies when employment based weighting is used.

Usage

  capWeight(weight, threshold = 500, exponent = 0.7)

Arguments

weight	input numeric vector
threshold	input numeric giving the threshold beyond which exp function should be applied
exponent	input numeric giving the exponent, typically below one as influence of big weights should be declined

Value

numeric vector of capped weights
