Hi folks,

I was searching via Google for tools to create formulas from data sets, what Excel provides me by way of a trendline formula was somewhat helpful but ended up not being quite precise enough for my needs. So I can across TuringBot and it can do a much better job . . . obviously.

So started using on simple X vs Y data and it seemed to do a good job . . . so I thought "I wonder if it can take all my data sets in one go"

I have X vs Y data at various fixed Z values, I want to be able to predict my Y value for given X and Z values. It seemed to be working until I started testing using the prediction tab, the values were obviously wrong. For a set X value when I vary the Z value the predicted Y value should increase or decrease with it . . . this wasn't happening. Increasing the Z would sometimes lead to a increasing Y sometimes a decreasing Y.

Hope this makes sense . . . What I think is happening is that TuringBot assumes all the data is one single series . . . when it is actually several different series. So I need it to do a regression in 2 dimensions . . . I think. Is this possible ?

My excel data looks like this, this may help to explain a little better:
