data sets (x,y), stored in columns of the Σ DAT matrix. For this application, you need to have at least two columns in your Σ DAT variable.
For example, to fit a linear relationship to the data shown in the table below:
xy 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 Σ DAT 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 Σ DAT, 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
