    Data probability/density




    Hi, hope im in the right place.

    Im trying to find the best way to characterize the different data on this space? to 3 draw regions (or lines with uncertainty) that will describe the data with the same color.

    I initially thought to take each data set (each color) and to make a plot of data probability (e.g. a region in which 90% of the data are inside it), but it will be biased toward the origin as a lot of data clustered there.

    Any suggestions?

    Re: Data probability/density

    can you fit a line to each group and inset a box reporting the slopes?

    Thanks, this can work, but the fitting will not be a linear line.

    Also, if i will fit a line to each group, how can i plot 95/66% interval around this line?

    Are you looking for a classification process in this space, probably with supervised learning?

    Not my area, but I wonder if you could translate into exponential distribution or what base you would need to generate each line. BGM, has a good point, though I am not familar with finding or defining clusters our groups. Always seems like a completely different area of stats or language than I know!
