Logistic Model, Bayesian Logistic Regression Model, Lamprey.Abstract
Based on the sexually deformable characteristics of the lamprey, this paper combines the logistic model and Bayesian logistic regression model to study the changes in its population numbers with food resources. In this paper, it is assumed that the growth rate is proportional to the food intake before the food reaches saturation. First, based on the traditional logistic model, this paper introduces the sex-related growth index and uses the least square method to fit it. Second, to investigate the relationship between food intake and gender ratio, this paper uses a Bayesian logistic regression model. The methodology of this paper provides a new idea to study the population size of sex-variable organisms, which has some credibility and novelty. At the same time, it also helps a lot in controlling the number of lampreys, which is favorable to the development of fisheries.
