Function
Lets you select and shade a region under a
function or distribution curve.
Regression The regression tools calculate and display a
selected regression model for the plotted
data. Regression is only available on Scatter
plots or X-Y line plots.
You can show or hide the following
regression models:
Linear (mx+b)
Linear (a+bx)
Median-Median
Quadratic
Cubic
Quartic
Power
Exponential
Logarithmic
Sinusoidal
Logistic (d=0)
Logistic (dƒ0)
Residuals The residuals tools display information
about the residuals of the selected model.
These tools are available when a scatter
plot and one or more lines, regressions, or
plotted functions are on the work area.
Show/Hide Residual Squares displays the
squares of residuals.
Show/Hide Residual Plot plots the
residuals against the explanatory variable.
The residual is the difference between the
observed value (data) and the value
calculated by a regression or function.
Plot Value Lets you graph a statistical value on the
axis. Examples of values that can be plotted
are a number, mean, median, and standard
deviation.
