Is it possible to get an actual number for pvalues instead of "<.0001"?
Solved! Go to Solution.
The reason why you see 0e+0 is most likely that the number of leading zeros after the decimal is higher than what you asked to display. Then JMP or any other software can only represent what is given by the calculations which is 0 then.
However, you should be aware of floating point arithmetic and what it is capable of calculating.1e-17 usually is the point where a floating point number cannot differentiate from 0, which means every non-zero value smaller than 1e-17 will be interpreted in calcualtions as zeros. That's (within others) for what symbolic math is good for, because you use symbolic values to deal with that, and the maths behind will calculate further on with mathematical rules rather than actual numeric calculations. Just a side note
In report table boxes, double-click on a p-value (or any number col box) to bring up the number format window. Change the setting from "PValue" to "Best".
Thanks but I have already tried that and the "<.0001" values just get converted to "0".
Thanks but I also tried that, even maxing out the width and decimal places and still converts is to simply "0" or "0.00000..........".
Try to edit the width of the number. But maybe there is a limit for how small numbers JMP will show.
Here's a really small p-value from an ANOVA (I use JMP 12.2).
Prob > F |
4,3e-179 |
Thanks again, I tried that as well and it still just converts it to "0". Actually the p value you got is exactly what I want as well. Not sure why I cannot convert it like you. I also am using JMP12.2.
Example:
Yes, I have tried all the different formats and different widths and decimal places. It all just converts to "0".
Thanks though.
