sample_size,
n_cat
)
param_current 
A numeric vector of regression parameters, in the order

obs_Ystar_matrix 
A numeric matrix of indicator variables (0, 1) for the firststage observed
outcome 
obs_Ytilde_matrix 
A numeric matrix of indicator variables (0, 1) for the secondstage observed
outcome 
X 
A numeric design matrix for the true outcome mechanism. 
Z 
A numeric design matrix for the firststage observation mechanism. 
V 
A numeric design matrix for the secondstage observation mechanism. 
sample_size 
An integer value specifying the number of observations in the sample.
This value should be equal to the number of rows of the design matrices, 
n_cat 
The number of categorical values that the true outcome, 
em_function_2stage
returns a numeric vector of updated parameter
estimates from one iteration of the EMalgorithm.
