In PROC HPLOGISTIC output, the 'Convergence Status' indicates 'Convergence criterion (GCONV=1E-8) satisfied.' What does this mean?
Select an answer to reveal the explanation.
Short Explanation and Infographic
Here's the deal — b is correct because GCONV is a gradient-based convergence criterion in PROC HPLOGISTIC. When the normalized gradient length is below GCONV=1E-8, the optimizer has found a stationary point of the log-likelihood function, indicating maximum likelihood estimates have been obtained.

Full Explanation
B is correct because GCONV is a gradient-based convergence criterion in PROC HPLOGISTIC. When the normalized gradient length is below GCONV=1E-8, the optimizer has found a stationary point of the log-likelihood function, indicating maximum likelihood estimates have been obtained. A describes non-convergence. C is wrong because a satisfied convergence criterion is a positive indicator, not a sign of poor fit. D is wrong because increasing GCONV makes the criterion less stringent, and the current convergence is satisfactory.
