WebThe cumulative distribution function is therefore a concave up parabola over the interval \(-1 WebThe cumulative distribution function (CDF or cdf) of the random variable X has the following definition: F X ( t) = P ( X ≤ t) The cdf is discussed in the text as well as in the notes but I wanted to point out a few things about this function. The cdf is not discussed in detail until section 2.4 but I feel that introducing it earlier is better.
