weighted.atkinson {acid} | R Documentation |
This function computes the Atkinson inequality index for a vector of observations with corresponding weights.
weighted.atkinson(x, w = NULL, epsilon = 1, wscale = 1000)
x |
a vector of observations. |
w |
a vector of weights. If |
epsilon |
inequality aversion parameter as denoted by Atkinson (1970). The default is epsilon=1. |
wscale |
a scale by which the weights are adjusted such that can be rounded to natural numbers. |
returns the selected Atkinson inequality index.
