1 2	estiML(x, a, method = "ATE", phi = expit, dphi = dexpit, phiinv = expitinv, maxit = 20)

`x`	A matrix of covariates of dimension n x p
`a`	A Vector a of 0s and 1s of dimension n
`method`	The method to be used "ATE" (default) or "IPW"
`phi`	A function that maps the real line onto the interval (0,1)
`dphi`	The derivative of `phi`
`phiinv`	The inverse of `phi`
`maxit`	The maximum number of iterations to be performed.
