Examine classification using logistic regression. In R console, type mtcars. The dataset mtcars is a generic dataset in R. This dataset comprises of fuel consumption and 10 aspects of automobile design and performance for 32 automobiles. Using only the variables am (0 = automatic, 1 = manual) and mpg, your task is to fit a logistic regression model. Complete the following steps using R. Create a scatter plot of am vs. mpg. Describe the relationship and explain why a simple...

The data set ”airquality” in the R datasets library has data on ozone concentration, wind speed, temperature, and solar radiation by month and day for May through September in New York. Attach airquality to your workspace and then construct side-by-side boxplots of Wind by Month. Month is a numeric variable in the airquality data frame. You can treat it as a factor by using the ”as.factor” function, e.g., > plot(Wind ∼ as.factor(Month)) Next, do an analysis of variance to determine...

R has a number of datasets built in. One such dataset is called mtcars. This data set contains fuel consumption and 10 aspects of automobile design and performance for 32 automobiles (1973-74 models) as reported in a 1974 issue of Motor Trend Magazine. We do not have to read in these built-in datasets. We can just attach the variables by using the code attach(mtcars) We can just type in mtcars and see the entire dataset. We can see the variable...
