Description
This function calculates K_M_var_factor, a numeric vector. Each entry in
this vector is a function of the number of times each unit is matched to, aka
K_M(i) (corresponding to Kiw, where M corresponds to M_matches. The calculation
in this function comes from Theorem 7, page 251 of Abadie and Imbens (2006)
Econometrica. The K_M_var_factor is an important component in the variance
estimation, created in the function estVarAI2006 in
estimateTau.
Usage
1
calcKMVarFactor(Kiw, M_matches)
Arguments
Kiw
A vector of times each unit is matched to
M_matches
Number of matches per unit for imputing potential outcomes,
as in Abadie and Imbens (2006).
Value
A numeric vector.
This function is exported for use in other packages.
