I am back into the mathematics for myself, and leave the systems for a while. Pick 3 and 4 aren't added, there are enough tools around. One to four visitors a day, next to robots and a hacker from time to time. I delete their comments and put their IP online.

Hi destinycreation,

I'll try to keep it simple.

Linear or nonlinear regression is a mathematic tool to predict time series, i.e a serie of numbers,in many domains as meteorology, economy,etc... Lotto numbers are a time series but scientists think that lottery cannot be forecasted with regression.

If you create a graph with your lottery numbers, you'll see a sawtooth like graph. Regression consists in finding the formula of the graph that can represent your numbers, the closest possible. We say that we model the curb. Having the formula for your lotto, you can then use it to predict the future, if the formula is simple. If not prediction will be difficult.

There are time series which can fit relatively easily when variations between numbers are small. That is the case when you play a lotto say with numbers between 1 and 10. You can use linear regression in that case. With Euromillions 5/50, with numbers between 1 and 50, variations are large and the curb is chaotic. Prediction is more difficult. We use nonlinear regression.

This matter is difficult for a non-mathematician to explain. I suggest that you visit the many sites on the web where you'll grasp more easily the subject. Looking at the graphs will help.

There is a lot more to say about regression but I cannot develop more for now. I hope that my explanations will help.

I hope somebody with mathematical background will come and explain better than I.

If you make a graph, you need values, names and such. You didn't say x nor y. Basically you said nothing at all.

There are time series which can fit relatively easily when variations between numbers are small.

You don't say what you mean by time series. What are the series, the values, the names ... ?

Or you can use a model to make for example 10 groups (you can use FFT for equalice numbers in groups). The model is not valid if you obtain one group with 30 numbers and others groups with 2 or 3 numbers. Here is a result example of good theorical model:

group 1: 12 numbers

group 2: 9 numbers

group 3: 8 numbers

group 4: 7 numbers

group 5: 5 numbers

group 6: 5 numbers

group 7: 4 numbers

Then you can use LinReg to this groups; if the LinReg function show a group to predict, then you know the numbers of this group.

My previous post was aimed atRL- RANDOMLOGIC .bob790 could also indicate the basic data of % correct and economic ROI or overall performance of the model / system.You may indicate too.Show this data means nothing for the user indicates ...
