Regression Calculation
In the explanations from “Linear Regression Graph” to “Logistic Regression Graph,”
regression calculation results were displayed after the graph was drawn. Here, each
coeffi cient value of the regression line or regression curve is expressed as a number.
You can directly determine the same expression from the data input screen.

Calculation of the Coeffi cient of Determination (r
2
) and MSe
You can use the
STAT
mode to calculate the coeffi cient of determination (r
2
) for quadratic
regression, cubic regression, and quartic regression. The following types of MSe calculations
are also available for each type of regression.
