Webb20 apr. 2024 · Independent variables, i.e. input variables, in logistic regression can be continuous or discrete data. In logistic regression, a distinction is made by looking at the values that the output variable will take. There are 3 types of logistic regression which are: Binary Logistic Regression: Dependent variables can take the values 0 or 1. WebbWe may account for the growth rate declining to 0 by including in the model a factor of 1 - P/K -- which is close to 1 (i.e., has no effect) when P is much smaller than K, and which is close to 0 when P is close to K. The …

Webb20 mars 2024 · @DougFir The logistic growth curve has some upper bound on it (i.e. some point which the model can not pass). The model estimates this to be 25.657. So, if I were to make predictions for very large x, you would see that the curve will get very close to 25.657 but will never touch it or pass it. There is more information here.
