To be able to plot Vector Functions: You must type vector functions using SQUARE BRACKETS [.] instead of the angle bracket in order to plot them. For other vector operations such as dot and cross product and magnitude , you must write the vectors using angle brackets . Below is a vector called v , a vector function, and a vector function is ...

We then have the following plot of the data with the fitted regression function: This is the best second-degree polynomial fit to the data, yet it is obviously not an appropriate model, as confirmed by the summary table. We can also run an interaction model (8.29) involving all three of our predictor variables and the same response variable.

Note here that R thinks of the ANOVA table as a matrix consisting of four rows and five columns. Of course, the number of rows depends on the number of predictors in the model. The first command adds all the values in the second column ("Sum Sq") of the table. The second command identifies MSE as the element in row 4 of column 3.

The plot will appear in the R interface on the graphics device. Refer back to the handout “Making a Scatterplot in R” regarding adding titles to your plot. To put a horizontal line on the plot through the origin, add the command > abline(h=0)

How does the scatter plot look when r is near –1? Describe the graph when r is near 0. Activity: Correlation and lines of best fit Get the Gizmo ready: Set r. to 1.00. (To quickly set a slider to a specific value, type the value into the text box to the right of the slider, and hit . Enter.) In a data set with a strong linear correlation, the ...

A plot of the residuals from the new model against the predictor shows that the variance is still constant: Unfortunately, nothing can be done about the outliers. Finally, a plot of the new regression line along with the transformed data shows that the linear fit is still appropriate:

By observing the plot we can make a "guess" as to what the values should be approximately, and then use an R method to solve the equation based on this rough data. By observing the plot …
