# Greater precision with regression?

I utilized my TI - 83 to locate the square regression of 2 information columns. The precision had not been close in all. So I attempted cubic and afterwards ultimately quartic regression. The precision still isn't close sufficient. Exists any kind of means I can boost the precision? I can not add anymore information, unfortunetly.

To resolve Henry is comment, my outlined information looks comparable to y = x ^ (1/3)

If, as you claim, it resembles $y=x^\frac{1}{3}$, after that you could attempt a power regression, which will certainly offer you a formula of the kind $y=ax^b$.
