Calculating the denominator of the group estimator.
Denominator( A, X, phi_hat, alpha = NULL, integral_bound = 10, include_alpha = TRUE )
A |
The treatment vector for units in the group. |
X |
The covariates for units in the group. |
phi_hat |
A list with two elements. The first one is a vector of coefficients of the ps, and the second one is the random effect variance. If the second element is 0, the propensity score excludes random effects. |
alpha |
This value of alpha is used to stabilize calculations. If include_alpha is set to TRUE, alpha needs to coincide with the alpha used for calculating the numerator. |
integral_bound |
If the propensity score includes a random effect, the integral in the denominator is calculated over the normal distribution of the random effects from - integral_bound to integral_bound. |
include_alpha |
If include_alpha is set to true, the probabilities in the denominator are divided by the specified value of alpha to stabilize the integral calculation. |
