### cumulative distribution function for non-normal distribution

From this article, I read that the author drew four versions of CDFs each plotted in different distributions (all four plots come from the same sample data) From these four plots, the author chooses ...

### Plotting groups of sample distributions as CDF with dispersion

Context I repeatedly run an experiment each repetition of which results in a sample of observations that I assume follow some distribution. (It is not important here what the distribution represents.)...

### Sampling from empirical distribution

I have a vector of y (min is > 0, max could be 1), for which, i have no idea what distribution is. But based on the data we have, vector y, we can get the empirical cumulative probability distribution,...

### Confidence interval for samples from an empirical distribution

I have data where a number of respondents are asked to rate the characteristic of a set of subjects on a scale of 1 to 100. A different number of respondents were asked to rate every subject, so we ...

### Comparison of empirical distributions in ciruclar/polar coordinates

I have 4 sets of 24 measurements of a polar variable (univariate). I want to use a statistical test, like the Kolmogorov-Smirnov test, to test whether said sets differ significantly from each other. ...

### What is the differences between estimating the margins and transforming them using cumulative distribution function

In copula models, the estimation of copula parameters is based on the pseudo-observations of the original data. As I understand, we can transform the margins using the cumulative distribution function ...

### Empirical distribution function for sample

I have a short question regarding empirical distribution function. We have a sample of $(1, 2.1, 1.5, 3)$. What's the value of the empirical distribution function for this sample $F_{4}$ at $x=2$? ...
Let $r_1 ≤ r_2 ≤ ... ≤ r_N$ denote an ORDERED set of N realizations of real numbers that are uniformly random on the number line from 0 to 1. Let $R_1 < R_2 < ... < R_N$ denote a set of ...
