Hello,dear Gretl Community. I'm doing a nonlinear estimation via the maximum likelihood method. I want to do a batch processing of data but in some cases the estimation don't satisfise tolerance (1,81899e-012), don't met the convergence criterion. Does anyone knows how it is calculated whether or not the model meets tolerance? An estimation that don't met tolerance; [image: Imágenes integradas 1] An estimation that met tolerance; [image: Imágenes integradas 2] [image: Imágenes integradas 3] Suggestion: I think it's calculated by adding up logslikelihood or gradients. But I do both and don't coincided with tolerance. Another question, How can I save automatically results? Beforehand, thank you for any help.
