Statistical Graphs and Calculations Chapter 7

P.118

Now you can press f and c to view variable characteristics.

For details on the meanings of these statistical values, see “Displaying Paired-Vari-

able Statistical Results”.

k Regression Calculation

In the explanations from "Linear Regression Graph" to "Power Regression Graph,"

regression calculation results were displayed after the graph was drawn. Here, the

regression line and regression curve is represented by mathematical expressions.

You can directly determine the same expression from the data input screen.

Perform the following key operation.

2(CALC)3(REG)

1(X)

Single variable regression parameters are displayed.

Next, you can use the following.

1 (X) ............ Linear regression

2 (Med) ........ Med-Med regression

3 (X^2) ......... Quadratic regression

[

1 (Log) ......... Logarithmic regression

2 (Exp) ......... Exponential regression

3 (Pwr) ......... Power regression

The meaning of the parameters that appear on this screen are the same as those for

“Linear Regression Graph” to “Power Regression Graph”.

k Estimated Value Calculation ( , )

After drawing a regression graph with the STAT Mode, you can use the RUN Mode

to calculate estimated values for the regression graph's

x and y parameters.

•Note that you cannot obtain estimated values for Med-Med graph and quad-

ratic regression graph.
