The USDA Integrated Pathogen Modeling Program - Global Fit (IPMP - Global Fit)
What is IPMP - Global Fit?
IPMP-Global Fit is an extension of the USDA Integrated Pathogen Modeling Program (IPMP). It is designed as a one-step direct kinetic analysis tool that constructs a tertiary model from the entire experimental data set of growth and inactivation. IPMP-Global Fit tries to analyze and fit the entire experimental data for both primary and secondary models and obtain the kinetic parameters that minimize the global error of the primary model. It differs from IPMP, which is design to analyze individual growth or inactivation curves. IPMP-Global Fit will analyze all isothermal growth or inactivation curves obtained under different conditions together, and try to derive kinetic parameters that are optimized for the entire data set. It is a tool developed to implement the one-step kinetic analysis methodology proposed by Huang (2015a, 2015b, and 2016).
What is required to use IPMP - Global Fit?
IPMP-Global Fit can be run under Microsoft Operating Systems (32 or 64 bit).
What models are included in IPMP - Global Fit?
IPMP-Global Fit includes four primary models for growth and survival and six secondary models. It will be expanded gradually to include more models.
