Pandas makes it very easy to output a DataFrame to Excel. We rather avoid this phrasing because ratio variables may hold negative values; the balance of my bank account may be negative but is has a fixed unit of measurement -Euros in my case- and zero means "nothing". This will allow us to see how the predicted probability of admission increases/decreases across different variables. Conclusion. Section 3 takes up those topics in statistics that derive their analytical power from the use of probability theory. Note: To learn more details for these statistics, see the introduction , algorithm and the interpreting results page. In this lesson we will take a look at how good tests are at picking up the presence or absence of disease, helping us choose appropriate tests, and how to interpret positive and negative results. indd Page i 12/3/09 2:51:50 PM user/Users/user/Desktop/Temp Work/00Novembe.
