    Is there a good tool for finding the best curve to fit my data?

    For a sample of data there is a coordinator empirical distribution. That would be "the" empirical distribution beyond discussed. It's the relevant empirical distribution. How much stats training do you have by the way?

    Back transformation of log transformed data

    That's a good point. But irrelevant because I don't think OP mentioned the IV should be normally distributed. They did say something about the DV being normally distributed - which is also not an assumption. We just need the error term to be normally distributed. And by "need" what I mean is...

    Is there a good tool for finding the best curve to fit my data?

    That just looks awful and the "What is different from other programs" section just makes it sound like the creator doesn't really understand statistics or at the very least is not good at explaining things. It sounds more like "let's try to convince people that don't know anything that we're...

    Is there a good tool for finding the best curve to fit my data?

    Sure! Essentially just using the empirical distribution as I suggested before. I just really still don't see why without a rigorous mathematical theoretical distribution to compare against they want to do something other than compare the mean or take a percentile ranking of some sort.

    I contend that you should at the absolute very least say "approximate normal" because there is literally no way it can be normally distributed. It also probably isn't even symmetric to be honest so I think you're just saying what you *want* to happen because the normal distribution is easy to...

    Question about the normality assumption

    It should be if the error term is normal then the sampling distribution is guaranteed to be normal.

    Math behind Pareto chart of standardized effects

    Right. But the degrees of freedom for every single 'feature' is the same so why do you think it matters here?

    Math behind Pareto chart of standardized effects

    The plots you're seeing just look to be using the absolute value of the t-statistic. These statistics don't change depending on if you're using standardized data or the raw data so that part doesn't really matter. It looks like they're just using "standardized effect" to mean that the sign of...

    Is there a good tool for finding the best curve to fit my data?

    Yeah. Or just use the empirical distribution derived from the data. Using a continuous distribution can be a useful approximation in some situations I still don't see a need for it here. A normal distribution seems wrong for that reason but there are others. It doesn't look symmetric even after...

    I don't personally think it looks great. For the area above the average nothing looks appropriate.

    How to calculate the maximum value of a normal distribution given the std dev?

    Honestly most regulars here probably don't know that. Most of the regulars don't have extensive mathematical statistics background.

    How to calculate the maximum value of a normal distribution given the std dev?

    Circles are involved. If you would see the proof that the normal distribution integrates to 1 you wouldn't be surprised about that. Edit: it involves considering the joint distribution of two independent normal random variables and then converting to polar coordinates to do the actual integration.

    Is there a good tool for finding the best curve to fit my data?

    Beta makes even less sense. What exactly do you mean by theoretical target because honestly I don't think there is a single theoretical target for the game. Like you said each player and play style impacts things so how do you determine that "target"? An empirical distribution is just the...

    I don't think a normal distribution is great here (for lots of reasons). Is there a reason the empirical distribution based on the data you have can't just work?

    Is there a good tool for finding the best curve to fit my data?

    Is there a particular reason you think there should be an explicit parameterized distribution for your situation? And what do you plan on doing once you have such a formula?
