Calculating and Graphing Paired-Variable Statistical Data
k k k k k Logistic Regression Graph
Logistic regression is best applied for time-based phenomena in which there is a continual
increase until a saturation point is reached.
The following is the logistic regression model formula.
y =

While the statistical data list is on the display, recall the SET UP screen to specify a LIST
("List 1" through "List 20") for "Resid List". Calculated residual data is stored in the specified
list.
The vertical distance from the plots to the regression model will be stored in the list.
Plots that are higher than the regression model are positive, while those that are lower are
negative.
Residual calculation can be performed and saved for all regression models.
# Any data already existing in the selected list is
cleared. The residual of each plot is stored in
the same precedence as the data used as the
model.
