Collins Models


The following is a muli-factor analysis model that can be used to record and track which variables are necessary for the spread of the Zika virus:





















This multi-factor analysis model is especially useful for modeling systems that include many variables, some of which must coexist, and some of which are sufficient for a certain phenomenon to continue. It is helpful for determining which factors are direct causes of an event and which are the beginning of a long chain of events.
Also, trend analysis-models can be used once a relationship between variables has been established as a predictive tool. A basic example:

This example is a very simple representation of what a scientist might analyze when looking at data trends. If the slope of the number of individuals affected follows the slope of the density of population in a certain ratio or pattern, if scientists can predict one variable in the future they can predict the other.

The next model that could be useful for the Zika virus is a Problem-centered Analysis:



This model is useful when human goals and actions need to be considered in a scientific or historical process. It is a realistic way that anyone can use to record the possible problems that arise to solutions to the original problem. This type of model could lead to a cost-benefit analysis model as well.
Overall, it seems that causal/functional and behavioral models are most useful when analyzing the interplay between variables, especially environment and human action, with regards to the spread of the Zika Virus.
