distributions - Intuitive explanation of Kolmogorov Smirnov Test ...

In statistics, an empirical distribution function (commonly also called an empirical Cumulative Distribution Function, eCDF) is the distribution function associated with the empirical measure of a sample. This cumulative distribution function is a step function that jumps up by 1/n at each of the n data points. Its value at any specified value of the measured variable is the fraction of observations of the measured variable that are less than or equal to the specified value. WebbI am making the cdf graph of mixture normal distribution in R.

Webb18.11.3 Comparing the empirical CDF to the theoretical CDF. A third visual approach is to estimate a cumulative distribution function (CDF) for the variable of interest from the data and compare this to the theoertical cumulative distribution function you’d expected for a normal distribution (as provided by pnorm()). WebbOne way to do that is to find the exponential distribution whose cumulative distribution function (CDF) best approximates (in a sense to be explained below) the ECDF of the data. The exponential CDF is p = Pr {X <= x} = 1 - exp (-x/mu). Transforming that to -log (1-p)*mu = x gives a linear relationship between -log (1-p) and x.
