Suppose there was an interest in studying which explanatory variables are indicative of patients experiencing a certain adverse event or not? Assume demographic characteristics, laboratory values at baseline and medications at start of the study are considered as explanatory variables. How would you set up to answer this question (explain how the response variable would be set up and which model you would use) (1)

1) A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.867 b=23.731 r2=0.403225 r=-0.635 Use this to predict the number of situps a person who watches 3 hours of TV can do (to one decimal place) 2)Based on the data shown below, calculate the regression line (each value to two decimal places) y =...

Homework 4 Use the hand span data that we collected in class for homework Suppose you want to buy someone a pair of love, but you do not know their love size. Usually, we do have a pretty good idea of the person's height. Let' asume that the right hand span is a rood indicator of the love size. So let find the best predictor of right hand span be on the person's height. Once we can predict the right...

USE R STUDIO The stackloss data frame available in R contains 21 observations on four variables taken at a factory where ammonia is converted to nitric acid. The first three variables are Air.Flow, Water.Temp, and Acid.Conc. The fourth variable is stack.loss, which measures the amount of ammonia that escapes before being absorbed. Read the help file for more information about this data frame. - Give a numerical summarization of each column of the dataset, then use boxplots to help illustrating...
