Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of.(from cars to computers, handyman, and even drones)
Goodluck!

go to [2nd] [0] then select [diagnosticon] and click [ENTER] then it atomatically adds it to the LinReg(ax+b)

Hi,

I don't know if you still need help with this problem but in case you do follow this link:

Good luck!

Hello,
The correlation coefficient does not have meaning (is not defined) for most regression models. Check you theory to make sure it exits for the sine regression.
An easy way to verify that, is to use the Command DiagnosticOn, accessible through the catalog [2nd][0] (CATALOG) . Press [X^-1] (D) to jump to first command that starts with D. Scroll down to DiagnosticOn, select it and press [ENTER]. Calculator replies Done.

Do your sine regression again. If the correlation coefficient has meaning for this type of regression, you will find it with the other statistical variables. You may have to scroll down the statistical variable list to verify the whole contents of the list.

Hope it helps.
Thank you for rating the solution.

### How do you do turn on diagnostics with a casio fx-9750g plus?

You don't do anything for the Casios.. If the correlation and determination coefficients have a meaning in the regression model (such as linear regression) they will be calculated and displayed automatically on the same screen where the regression equation is displayed. However if the regression model has no such coefficients nothing will be displayed.

### My r^2 for regressions isnt being calculated by default

The truth of the matter is that the correlation factor coefficient, and determination coefficients are not defined for all regression models. If they are not defined, they will not be displayed among the statistics. It depends on the model you are trying to fit to your data.

### How to calculate the coefficient of linear correlation using casio cfx-9850 Ga plus

Although the coefficient of correlation is well defined for a few regression models, you do not calculate it directly because your calculator does that for you.
I could just tell you that it is displayed along with the statistical results (equation of best fitting curve, ) but if you do not know how to do that you will just shoot my post. If you know how to do a linear regression, stop right here and ignore what follows.

For those interested: How to do a regression on the calculator
I am sorry but I will have to assume that you know how to enter the data through the [MENU][STAT].

1. After you finish entering all the data
2. Press [F1:Graph], select Gph1, Gph2, or Gph3.
3. Once the graph of the experimental data is drawn, you will have access to the diverse regression models.
5. [X:Linear]
6. [Med-Med],
8. [Cubic;X^3]
9. [Quartic: X^4].
10. Press [F6] to scroll right to access the others
11. [Logarithmic:LOG],
12. [Exponential :EXP],
13. [Power :Pwr] and
14. [Sinusoidal: Sin]
After you select a model and press [EXE], the screen displays the equation and its various coefficients, a correlation coefficient if it has meaning, etc.
On that same screen, you have a menu option [F6:Draw]. If you select it, the regression curve will be drawn on the same screen as your statistical graph. This allows you to judge if the fit is good. If it is not, you have the option to choose another model.
The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.

### How to do matrix with variables?

Hi,
If I understand correctly you want to perform matrix calculations on matrices the coefficients of which may be numbers and/or letters (variables, parameters). While you can calculate on numerical matrices, you cannot do so with matrices with non numerical coefficients. this calculator does not know symbolic algebra.

For symbolic algebra and calculus you would need a calculator with a CAS, Computer Algebra System. Exemples of those are the TI89, Ti92, Ti Voyage 200 PLT, The Casio FX-Algebra, the Casio ClassPad, HP48S/X/G/GX/G+, HP49G/49G+, HP50G, HP48GII etc.

Hope it Helps.
Thanks for using FixYa and for rating this solution.

### I am not able to do some functions on my TI-84 Plus calculator, such as: coefficient correlations. I was told I may need to reset my calculator. How do I do that?

To have the coefficient correlation show up when you calculate a regression, you must first turn diagnostics on.

The way to do this is press 2nd then zero. You are now in the catalog. Go to the d's in the alaphbetic list, highlight "diagnostic on" and press enter. You will be taken back to the home screen press enter and you get the word "done". The diagnostic is not on unless you get the word "done".

Now when you calculate a regression, the correlation coefficient will show up. It is designated as r = on the home screen.
