cML_SdTheta function

Standard Error of Estimated Theta

Internal function of mr_cML. Get the standard error of estimated theta from constrained maximum likelihood.

cML_SdTheta(b_exp, b_out, se_exp, se_out, theta, b_vec, r_vec)

Arguments

• b_exp: Vector of estimated effects for exposure.
• b_out: Vector or estimated effects for outcome.
• se_exp: Vector of standard errors for exposure.
• se_out: Vector of standard errors for outcome.
• theta: Estimated theta from cML.
• b_vec: Estimated vector of b from cML.
• r_vec: Estimated vector of r from cML.

Returns

Standard error of theta.

Examples

# First get estimates:
MLE_result = cML_estimate(b_exp = ldlc,b_out = chdlodds,se_exp = ldlcse,
se_out = chdloddsse, K = 5)

# Calculate standard error:
cML_SdTheta(b_exp = ldlc,b_out = chdlodds,se_exp = ldlcse,
se_out = chdloddsse, theta = MLE_result$theta, b_vec = MLE_result$b_vec, r_vec = MLE_result$r_vec)
