    Fit Distribution

    Hello I have plotted two different data sets.
    Yfrog Image : yfrog.com/0afitdistributionforblueap
    Blue and Red data sets
    For every different value on axis x I have taken only 10 measurements as it takes so much time for the experiment to run.
    I would like to fit two distributions for these two data sets. One for each one. I do not know what function to use in matlab. If I got it right I have to
    a)pick one distribution that looks that it will fit (how do you do that)
    and
    b) change the parameters of the distribution to fit as much with my data. How do you do that??\

    I would like to thank you all for your help and contribution.
    Best Regards
    Alex

    Please provide more information about what you are trying to do. (by the look of the data the ble is a simple linear transformation of the red so there is really only one data set).

    Fitting Distribution

    I would like to say the red dots follow this distribution and also follow this equation

    y=(something)*+-(x)\

    I would like to thank you for your help

    That still makes no sense.

    What does this data represent and what form of relation between x and y should we exoect to see?

    This is a game between two populations. The total number of players remains constant.
    As the parameter b changes the number of cooperators and defectors (the two different populations of this game) change. The sum cooperators+defectors=constant (total population).
    I would like to express somehow based on the figure posted above how b affects the number of cooperators and defectors.
    I would like to thank you in advance for your help.
