This study presents a method for fitting Gaussian diffusion models to biological growth data. The approach uses approximations of mean and variance functions for accurate stochastic modeling.
Area of Science:
- Biosciences
- Stochastic Modeling
- Mathematical Biology
Background:
- Dynamic phenomena in biosciences require robust stochastic models.

- Existing methods may not fully capture the nuances of dynamic biological processes.
Purpose of the Study:
- To develop a methodology for empirically fitting Gaussian diffusion processes to biological data.
- To provide a framework for stochastic modeling of dynamic phenomena, particularly in biosciences.
- To validate the proposed method using both simulated and real-world biological data.
Main Methods:
- Developing approximations for the mean and variance functions of Gaussian diffusion processes.
- Empirical fitting of the stochastic model to sample data from dynamic growth phenomena.
- Utilizing statistical techniques for model parameter estimation.
Main Results:
- Successfully fitted a Gaussian diffusion process to dynamic growth data.
