the program CRMC developed in Chapter 10. Next, save this matrix into the
statistical matrix ΣDAT, by using function STOΣ.
Finally, launch the data fit application by using: ‚Ù˜˜@@@OK@@@ . The
display shows the current ΣDAT, already loaded. Change your set up screen
to the following parameters if needed:
Press @@@OK@@@, to get:
2: Correlation: -0.996624999526
3: Covariance: -6.23350666124
The best fit for the data is, therefore, y = 3.995 e

move to the fourth option using the down-arrow key ˜, and press @@@OK@@@.
The resulting input form contains the following fields:

these options apply only when you have more than two

program by checking the appropriate field using [ CHK]
when that field is selected.
Many of these summary statistics are used to calculate statistics of two
variables (x,y) that may be related by a function y = f(x). Therefore, this
program can be thought off as a companion to program
