From 95178837d3f91e84837628446b5fd468179af2b9 Mon Sep 17 00:00:00 2001 From: Johannes Ranke Date: Tue, 4 Jun 2019 15:09:28 +0200 Subject: Additional algorithm "d_c", more tests, docs The new algorithm tries direct optimization of the likelihood, as well as a three step procedure. In this way, we consistently get the model with the highest likelihood for SFO, DFOP and HS for all 12 new test datasets. --- docs/articles/web_only/NAFTA_examples.html | 103 ++++++++++++++--------------- 1 file changed, 48 insertions(+), 55 deletions(-) (limited to 'docs/articles/web_only/NAFTA_examples.html') diff --git a/docs/articles/web_only/NAFTA_examples.html b/docs/articles/web_only/NAFTA_examples.html index 4d9e9b2d..7f3cc76b 100644 --- a/docs/articles/web_only/NAFTA_examples.html +++ b/docs/articles/web_only/NAFTA_examples.html @@ -30,7 +30,7 @@ mkin - 0.9.49.4 + 0.9.49.5 @@ -88,7 +88,7 @@

For this dataset, the IORE fit does not converge when the default starting values used by mkin for the IORE model are used. Therefore, a lower value for the rate constant is used here.
