A random variable (stochastic variable) is a type of variable instatisticswhose possible values depend on the outcomes of a certain random phenomenon. Since a random variable can take on different values, it is

1, or 2 if the random variable Y is the number of heads we get from tossing two coins. We could have no heads, one head, or both heads on a two-coin toss.
For example, the number of heads in 10 coin flips or the number of customers arriving at a store in an hour are cases of discrete random variables. In these scenarios, you can list all possible outcomes, such as zero, one, two, and so on. It's more likely that discrete probability d...

Because the null type has no name, it is impossible to declare a variable of the null type or to cast to the null type. The null reference is the only possible value of an expression of null type. The null reference can always undergo a widening reference conversion to any reference ...
Incrementally learning new information from a non-stationary stream of data, referred to as ‘continual learning’, is a key feature of natural intelligence, but a challenging problem for deep neural networks. In recent years, numerous deep learning meth

As expected, the DNA fragmentation "profiles" of the healthy individuals were more ordered and much less variable than those of the cancer patients. Besides simply spotting the presence of a cancer, the new blood test was between 61% and 75% accurate in determining the tissue of o...
selected to serve as an interpretative type when the holotype, lectotype, or previously designated neotype, or all original material associated with a validly published name, is demonstrably ambiguous and cannot be critically identified for purposes of the precise application of the name of a taxon...
