data sets (x,y), stored in columns of the ΣDAT matrix. For this application,

you need to have at least two columns in your ΣDAT variable.

For example, to fit a linear relationship to the data shown in the table below:

x y

0 0.5

1 2.3

2 3.6

3 6.7

4 7.2

5 11

• First, enter the two columns of data into variable ΣDAT by using the matrix

writer, and function STOΣ.

• To access the program

3. Fit data.., use the following keystrokes:

‚Ù˜˜@@@OK@@@ The input form will show the current ΣDAT,

already loaded. If needed, change your set up screen to the following

parameters for a linear fitting:

• To obtain the data fitting press @@OK@@. The output from this program,

shown below for our particular data set, consists of the following three

lines in RPN mode:

3: '0.195238095238 + 2.00857242857*X'

2: Correlation: 0.983781424465

1: Covariance: 7.03
