The PDF is the density of probability rather than the probability mass. The concept is very similar to mass density in physics: its unit is probability per ...

I will use the convention of upper-case P for discrete probabilities, and lower-case p for PDFs. With the PDF we can specify the probability that the random ...

You've decided to flip a coin. What's the probability the coin will come up heads? Tails? What about heads 10 times in a row? What about heads, then, tails, ...

Probability Density Function. Theorem. The probability density function (PDF) is the derivative of the cumulative distribution function (CDF):. pX (x) = dFX (x).

We first look at general probability density functions and their expected value and variance, then look at special probability density functions; specifically, ...

The density function is shown in Figure 4.6. Figure 4.6. The pdf for a uniform distribution. Page 21. 21.

A probability density function (PDF) explains which values are likely to appear in a data-generating process at any given time or for any given draw. A ...
