k Paired-Variable Statistical Calculations In the previous example under "Displaying the Calculation Results of a Drawn Paired-Variable Graph", statistical calculation results were displayed after the graph was drawn. These were numeric expressions of the characteristics of variables used in the graphic display. These values can also be directly obtained by displaying the List Editor and pressing 2(CALC)2(2-VAR). After this, pressing f or c scrolls the statistical calculation result display so you can view variable characteristics. For details on the meanings of these statistical values, see "Displaying the Calculation Results of a Drawn Paired-Variable Graph" (page 6-21). k 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 coefficient 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. Pressing 2(CALC)3(REG) displays a function menu, which contains the following items. • {ax+b}/{a+bx}/{Med}/{X2}/{X3}/{X4}/{Log}/{aebx}/{abx}/{Power}/{Sin}/{Logistic} ... {linear regression (ax+b form)}/{linear regression (a+bx form)}/{Med-Med}/{quadratic regression}/{cubic regression}/{quartic regression}/{logarithmic regression}/{exponential regression (aebx form)}/{exponential regression (abx form)}/{power regression}/ {sinusoidal regression}/{logistic regression} parameters Example To display single-variable regression parameters 2(CALC)3(REG)1(X)1(ax+b) The meanings of the parameters that appear on this screen are the same as those for "Displaying Regression Calculation Results" and "Linear Regression Graph" to "Logistic Regression Graph". 6-23
