For the plot in density, the user can use the arguments histo and demp to specify if he wants the histogram using the function hist, the density plot using the function density, or both (at least one of the two arguments must be put to "TRUE" ).

WebbThe cdf is an increasing step function that has a vertical jump of at each value of x equal to an observed value. The cdf is also referred to as the empirical cumulative distribution function (ECDF). You can use any number of CDFPLOT statements in the UNIVARIATE procedure. The components of the CDFPLOT statement are as follows. variables 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. irish term gom
