Understanding Empirical Data Distribution
"We can approximate $p (x, y) = p (x) p (y | x)$ using the empirical data distribution
$p (x, y) = \frac{1}{N} \sum_{n = 1}^{N} δ_{x_{n}} (x) δ_{y_{n}} (y) "$
In another part of the paper they say $p (y | y_{n}) = δ_{y_{n}} (y)$ .
I have some background in probability but none in statistics; I was able to figure out what an Empirical CDF is, but not a pdf like here, so I'm not sure exactly what the authors are doing. Does the $δ$ refer to the Dirac delta distribution?

Let T be the time needed to complete a job at a certain factory. By using the historical data, we know that
$P (T \leq t) = {\begin{cases} \frac{1}{16} t^{2} & f o r 0 \leq t \leq 4 \\ 1 & f o r t \geq 4 \end{cases}$
a. Find the probability that the job is completed in less than one hour, i.e., find $P (T \leq 1)$ .
b. Find the probability that the job needs more than 2 hours.
c. Find the probability that $1 \leq T \leq 3$ .

As data distributions tasks can take various shapes and forms, always start with statistical reports as these may help you to find the answers that you require. See data distribution examples next to learn about the most suitable methodology for your particular case. There may be equations and a list of assumptions that are usually presented as word problems. If you have one in your school's textbook, compare it with the questions below and look for similarities. Since we are dealing with probability, do not forget to look into practice C Data distributions answers.
