The regression line for a residual plot is a horizontal line. III. A definite pattern in the residual plot is an indicator that a nonlinear model will show a better fit to the data than the straight regression line.

Calculate the horizontal distance that the ball will go during the time it takes to fall to the target. (R = vxtfall) Construct a graph of average horizontal range vs. initial velocity for all data sets. Remember to think carefully about which is the independent or dependent variable.

Horizontal Lines, recall, are lines that run straight across from left to right. A horizontal line has zero slope. This is because the change in y is zero and zero divided by anything is zero! Example: Find the slope of the horizontal line through the points (0,5);(10,5) Vertical …

There are two special cases of lines: a horizontal line and a vertical line. In a horizontal line like the one graphed to the right, notice that between any two points, the change in the outputs is 0. In the slope equation, the numerator will be 0, resulting in a slope of 0. Using a slope of 0 …

Instead of using the default x-axis line, I'll replace it with a makeshift horizontal line using the geom_hline function. # Make final adjustments to the plot in R. # Override previous specifications for x axis line.

The line will appear superimposed over the data. You can also just type the actual values for the estimated intercept and slope if you prefer. To save your plot, click anywhere on the plot, then on the menu bar choose “File,” then “Save as.” Choose the format in which you want to save the plot, then where you want to save it on your drive.

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) You would follow a similar procedure to plot the residuals against the fitted values. Just replace Data$ACT with Data$fitted.values in the plot() command, and change the value of xlab to "Fitted Values".

Notice that the R has gone up a lot and is now significant, and the residuals plot looks fine. Let us have a look at the regression line. We saved the predicted scores (PRE_1), so we can plot their means against dose of the drug: Click Graphs, Line, Simple, Define. Select Line Represents Other statistic and scoot PRE_1 into the variable box.
