Jul 19, 2011 · The CDF's are the black and blue lines, whereas the survival function (1-CDF) is the orange line. The likelihood of finding 200 mm of rainfall is related to a probability distribution.

May 16, 2016 · The CDF (cumulative distribution function) is more convenient as the function plotted is increasing along the x-axis and the y-axis. Extracting the quantile, that is, the variate from CDF is …

This function, $F (x)$, is called the "cumulative distribution function," or CDF. It is defined in this manner, so the relationship between CDF and PDF is not coincidental -- it is by design.
