Physical Activity & BMI

This study finds that the inverse logarithmic model is more accurate in describing the relationship between physical activity and body mass index than is the inverse linear model. This study also finds that the inverse logistic model is best suited in describing the relationship between the two variables.

Planetary-Rotation Periods

This paper uses an inductive method to investigate the factors responsible for variations in planetary-rotation periods. I found that velocity, acceleration, and radius are the most important variables in explaining rotation periods.
