RA sproj medical costs for children

Using data from your regular jobs can be useful for a student project. You have a good understanding of which explanatory variables are likely to affect the response variable, as well why certain relations may or may not hold. One might think that obese children have higher medical costs than average weight children. The statistical analysis shows this is not true, and the reasoning in this project justifies the results. The co-plots are easy to form in R. One can read the Excel data into a R data frame and form a co-plot.
