It all depends on what data set you're working with. There a quite a number of different regression analysis models that range the gambit of all functions you can think of. Obviously some are more useful than others. Logistic regression is extremely useful for population modelling because population growth follows a logistic curve. The final goal for any regression analysis is to have a mathematical function that most closely fits your data, so advantages and disadvantages depend entirely upon that.
Absolute growth rate(agr) curve enables us to express the growth of organisms in terms f growth rate. In most organism, agr increases steadily until reaches a maximum and then, gradually falls. Agr is a bell-shaped curve.

Logistic growth
Logistic growth curve shows a carrying capacity, where the population grows exponentially at first, then levels off as it reaches the maximum sustainable population size for the environment.
population growth begins to slow down
The classic "S" shaped curve that is characteristic of logistic growth.

Logistic growth occurs when a population's growth slows and then stops, fallowing a period of exponential growthex; a lot of familiar plant and animal populations fallow a logestic growth curve.
Logistic growth occurs when a population's growth rate decreases as the population size approaches the carrying capacity of its environment. This type of growth involves an initial rapid increase in population size followed by a slowing down as resources become limited. Logistic growth is characterized by an S-shaped curve.
The life history pattern in which population growth is logistic is known as the logistic growth model. This model describes how populations initially grow exponentially, but eventually reach a carrying capacity where growth levels off due to limited resources or other constraints. The logistic growth model is often represented by an S-shaped curve.
what letter is used to refer to the characteristic shape of the logistic growth curve
A population's growth curve most closely resembles an "S" shaped curve, known as the logistic growth curve. Initially, the curve rises slowly as the population grows, followed by a period of rapid growth, before leveling off as the environment's carrying capacity is reached and growth stabilizes.
