The cumulative distribution function of x
WebWhen we plot a continuous distribution, we are actually plotting the density. The probability for the continuous distribution is defined as the integral of the density function over some … WebThe cumulative distribution function (CDF or cdf) of the random variable \(X\) has the following definition: \(F_X(t)=P(X\le t)\) 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.
