What are the most important things to consider when identifying
a model to fit a set of data? Be sure to list as many
characteristics as you can, but don't be afraid to share any
thoughts, ideas, or uncertainties you may have about a particular
model. If you're unsure about something, just ask some clarifying
questions to help you get a better idea of what the model's key
features are. Your post must have a minimum of 5 sentences.
