If the conditional distribution of given is a continuous distribution, then its probability density function is known as the conditional density function. [1] The properties of a conditional distribution, such as the moments , are often referred to by corresponding names such as the conditional mean and conditional variance .
In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value evaluated with respect to the conditional probability distribution. If the random variable can take on only a finite number of values, the "conditions" are that the variable can only take on a subset of ...
In probability theory, the chain rule [1] (also called the general product rule [2] [3]) describes how to calculate the probability of the intersection of, not necessarily independent, events or the joint distribution of random variables respectively, using conditional probabilities. This rule allows one to express a joint probability in terms ...
The resulting limit is the conditional probability distribution of Y given X and exists when the denominator, the probability density (), is strictly positive. It is tempting to define the undefined probability P ( A ∣ X = x ) {\displaystyle P(A\mid X=x)} using limit ( 1 ), but this cannot be done in a consistent manner.

And that distribution will count toward your required minimum distribution for your IRA(s). The Secure 2.0 Act updated the rules on QCDs to add an inflation adjustment starting in 2024. Last year ...
Born between July 1, 1949, and December 31, 1950: RMDs should have started at age 72. Born before July 1, 1949: RMDs should have started at age 70 and 1/2. In most cases, RMDs must be taken by Dec ...
The law of total probability extends to the case of conditioning on events generated by continuous random variables. Let (,,) be a probability space.Suppose is a random variable with distribution function , and an event on (,,).
