I am using the phbirths data in the faraway package in R. I want to: 1) create a plot of the birth weight vs the gestational age and I want to colour code the points based on the mothers smoking status to determine whether or not smoking affects the babies. 2) fit a simple model (one regression line) along with both the main effects (parallel lines) and interaction (non parallel lines) ANCOVA model to the data and find out which...

The dataset ’anorexia’ in the MASS package in R-Studio contains data for an anorexia study. In the study, three treatments (Treat) were applied to groups of young female anorexia patients, and their weights before (Prewt) and after (Postwt) treatment were recorded. The three treatments adminstered were no treatment (Cont), Cognitive Behavioural treatment (CBT), and family treatment (FT). Determine at the 5% significance level if there is a difference in mean weight gain between those receiving no treatment and those receiving...

The R library faraway contains the pima dataset. We will fit a model with test as a response and bmi (only) as a predictor to see the relationship between the odds of a patient showing signs of diabetes and his/her bmi. The odds o and probability p are related by: o = p/(1-p), p = o(1+o) Using the GLM function: a. Please estimate the amount of increase in the log(odds) when the bmi increases by 10. b. Give a 95%...

a study of prostate cancer was initiated in Des Moines, Iowa. A total of 1,000 men, 55-64 years of age, with no prior evidence of prostate cancer were enrolled in the study. Each year during the study, the men being observed were examined and tested for the presence of prostate cancer. The results of the annual exam revealed: 10 cases confirmed at the 1st exam, 15 additional cases at 2nd exam, 20 additional cases at 3rd exam, 25 additional cases...
