Relative Error | The relative error is a measure of the error between | ||
| predicted values and actual values based on the specified | ||
| Fit. A smaller number means a better fit. |
| |
| The relative error is stored in a variable named RELERR. | ||
| The relative error provides a measure of fit accuracy for | ||
| all fits, and it does depend on the Fit model you have | ||
| chosen. |

Plot type (1VAR) STATPLOT enables you to specify either a histogram or a
Histogram width HWIDTH enables you to specify the width of a histogram bar. This determines how many bars will fit in the display, as well as how the data is distributed (how many values each bar represents).
Histogram range HRNG enables you to specify the range of values for a set of histogram bars. The range runs from the left edge of the leftmost bar to the right edge of the rightmost bar. You can limit the range to exclude any values you suspect are outliers.
Plotting mark (2VAR)
Connected points (2VAR)
S1MARK through S5MARK enables you to specify one of
five symbols to use to plot each data set. Press to change the highlighted setting.
CONNECT (on the second page), when checkmarked, connects the data points as they are plotted. The resulting line is not the regression curve. The order of plotting is according to the ascending order of independent values.
