This page will report any news that relates to the theory and practice of Data-Based Mechanistic Modelling or the CAPTAIN Toolbox.
I have been developing new RIVCBJDD, RIVCBJFDID and RIVCBJFD tools for the CAPTAIN Toolbox, specifically in relation to their use in my new book The Art and Craft of Data-Based Modelling, Forecasting and Control, which is due to be published in 2026. RIVCBJDD is for the estimation of continuous-time TF models with multiple-inputs and different denominators; while RIVCBJFDID and RIVCBJFD are for the identification and estimation of continuous-time models with multiple inputs and fractional (non-integer) time delays between the inputs and the output. The Technical Notes on these can be accessed using the buttons below. This is an upgrade (2/4/2026) of earlier TN posts on new CAPTAIN Tools.
