DA_FDN2M1M2: Data Analysis for Combining (N2,M1) + (N2,M2)

Description

The main function to solve the estimating equations constructed by combining pair (N2,M1) and (N2,M2). Since there is just one case data, no selection bias needed.

Usage

DA_FDN2M1M2(realdata_covariates, realdata_alpha, subset_2, subset_4, p, beta0)

Arguments

realdata_covariates

a list contains the following data matrics: CASEZ_2, CASEZhat_2, CASEZhat_22, CONTZ_1, CONTZhat_1, CONTZhat_2, CONTZhat_22

realdata_alpha

a list contains the following data matrics: prob_case_22, prob_cont_1, prob_cont_2, pwt_cont_2

subset_2

A vector of 1:(p-2), which is the subset of $\hat{Z}_{21}$, i.e. $\hat{Z}_{21}^\star$ in equation (10) of Huang(2014). $\hat{Z}_l$ may be highly correlated with Z_d, so it is removed in the estimation. For the view of including more information, you can use the whole dataset.

subset_4

A vector of 1:(p-2), which is the subset of $\hat{Z}_{22}$.

p

number of parameters.

beta0

an initial parameter for solver "nleqslv".

Value

A list of estimator and its standard deviation.

Details

The function solves estimating equation based on (N2,M1) and (N2,M2), see Huang(2014).
