Description dudson 2008-03-20 18:18:27 UTC
With diagrams it's now possible to add a formulae. But it can't do more than
lineaire regression.
Please add more like goniometric regressions, exponential, multiple (e.g. Y =
X^5) and others.
Also a chance to define a formulae with elements inserted as letters or groups
of letters and that values are being sought for whitch r² is close to 1 as possible.

one for you.
Comment 2 dudson 2013-09-27 21:06:18 UTC
Being able to do polynomials would be really useful.
They are used as something of a general purpose solution when there is not much else.
Comment 3 Edwin Sharp 2014-03-06 17:22:08 UTC
Available trend line types: linear, logarithmic, exponential, power.

The request for polynomial regression is valid, but already tracked in bug 20819.
