pi_vals |
A vector of non-negative numerics that sums to one. The current values of the mixing proportions. |
z2 |
A vector of numerics. The current values of the unobserved confounders. |
xi |
A positive numeric. The current value of the variance inflation factor. |
betahat_ols |
A vector of numerics. The OLS regression coefficients. |
S_diag |
A vector of positive numerics. The standard errors. |
alpha_tilde |
A matrix of numerics. The estimates of the coefficients of the confounders. |
a_seq |
A vector of numerics (usually non-positive). The lower bounds of the uniform mixing densities. |
b_seq |
A vector of numerics (usually non-negative). The upper bounds of the uniform mixing densities. |
lambda_seq |
A vector of numerics greater than 1. The penalties on the mixing proportions. |
degrees_freedom |
A positive scalar or a vector of positive
scalars the length of |
