Curve fitting programs

Post: 5. Have to check if there is some equal code in 42S Those first three would be functions for working with files in extended memory I'm guessing this program stores the stat data there, rather than just accumulating sums. There's no direct equivalent on the 42S, but you can get similar results by using a matrix to store stat data.

Combining that with the program in Kolb's book would probably be the simplest approach. Post: 6. Post: 7. Post: 8. I was just thinking to do some simple curvfit since I use to do it in excel for different sensors like NTC resistors etc. Namirs program seems quite advance. I just need to analyze say 10 to 15 X Y values.

Looking at Colbs program it seems not that hard to translate to HP42 code. Im not familiar to curvfit theory just a user. Post: 9. Maybe you should now explain what exactly you are looking for. The term "multiple" in your subject line is a bit misleading here. If you say you have only X and Y-values you are obviously NOT looking for a program that does a multiple sic!

The latter means that the result is a linear combination of multiple independent variables, i. So it looks like you need a program that calculates multiple styles of regression functions, e. Such a program is included in the HP Standard Applications booklet that comes with the calculator. And it is also listed on this website but without documentation and instructions. Post: Yes thats more what Im looking for.

When working in excel I feed in some measured X and Y values and then select what regression fits the values best. Then I can use the function to get values from different sensors etc. What I thought however when looking at Kolb's program was that I could feed in X and Y values and the program would select the function with best fit automatically. Is this the case?

Of course I can't say anything about the program in the Kolb book, but if you only want to fit an XY-curve with two parameters and choose between a linear, logarithmic, exponential and power fit, and you already have a DM42, why do you think you need a special program?
