w_m_normalY function

Compute E-step for Binary Mediator Misclassification Model Estimated With the EM Algorithm

Note that this function should only be used for Normal outcome models.

)

Arguments

• mstar_matrix: A numeric matrix of indicator variables (0, 1) for the observed mediator M*. Rows of the matrix correspond to each subject. Columns of the matrix correspond to each observed mediator category. Each row should contain exactly one 0 entry and exactly one 1 entry.
• pistar_matrix: A numeric matrix of conditional probabilities obtained from the internal function pistar_compute. Rows of the matrix correspond to each subject and to each observed mediator category. Columns of the matrix correspond to each true, latent mediator category.
• pi_matrix: A numeric matrix of probabilities obtained from the internal function pi_compute. Rows of the matrix correspond to each subject. Columns of the matrix correspond to each true, latent mediator category.
• p_yi_m0: A numeric vector of Normal outcome likelihoods computed assuming a true mediator value of 0.
• p_yi_m1: A numeric vector of Normal outcome likelihoods computed assuming a true mediator value of 1.
• 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 observed mediator matrix, mstar_matrix.
• n_cat: The number of categorical values that the true outcome, M, and the observed outcome, M*, can take.

Returns

w_m_normalY returns a matrix of E-step weights for the EM-algorithm. Rows of the matrix correspond to each subject. Columns of the matrix correspond to the true mediator categories $j = 1, \dots,$ n_cat.
