zeta | R Documentation |
Of limited interest to most users, the zeta function plays an internal role in 2-sample and stratified sensitivity analyses. The zeta function is equation (8), page 495, in Rosenbaum and Krieger (1990).
zeta(bigN, n, m, g)
bigN |
Total sample size in this stratum. |
n |
Treated sample size in this stratum. |
m |
The number of 1's in the vector u of unobserved covariates. Here, u has bigN-m 0's followed by m 1's. |
g |
The sensitivity parameter |
The value of the zeta function.
The zeta function is called by computep. The zeta function is from the senstrat package.
