Suppose you have two random variables, X and Y and their joint probability distribution function is f(x, y) over some appropriate domain.

Then the marginal probability distribution of X, is the integral or sum of f(x, y) calculated over all possible values of Y.

What is marginal probability function?

If f(x, y) is the joint probability distribution function of two random variables, X and Y, then the sum (or integral) of f(x, y) over all possible values of y is the marginal probability function of x. The definition can be extended analogously to joint and marginal distribution functions of more than 2 variables.


How do marginal effects be interpreted?

Marginal effects represent the change in the predicted probability of an outcome occurring as a result of a one-unit change in an independent variable, holding all other variables constant. In simpler terms, they quantify the impact of a specific predictor on the dependent variable. For example, in a logistic regression, a marginal effect of 0.05 for a variable means that increasing that variable by one unit increases the probability of the outcome by 5%. This interpretation helps in understanding the practical significance of each predictor in the model.


What is the Relationship between marginal and conditional and joint probabilities?

The joint probability of two discrete variables, X and Y isP(x, y) = Prob(X = x and Y = y) and it is defined for each ordered pair (x,y) in the event space.The conditional probability of X, given that Y is y is Prob[(X, Y) = (x, y)]/Prob(Y = y) or equivalently,Prob(X = x and Y = y)/Prob(Y = y)The marginal probability of X is simply the probability of X. It can be derived from the joint distribution by summing over all possible values of Y.

What does A marginal rating on a security assessment indicates what?

A marginal rating on a security assessment indicates that the security controls in place are insufficient to adequately protect the organization from potential threats and vulnerabilities. It suggests that while some measures are in place, they are not effectively mitigating risks, leading to a higher probability of security incidents. Organizations receiving a marginal rating should prioritize improvements to their security posture to address identified weaknesses.

What is meant by marginal non marginal complete incomplete syndesmophytes?

In regards to marginal vs. non-marginal syndesmophytes. Marginal syndesmophytes (intervertebral bony bony bridges) are more commonly seen in ankylosing spondylitis. Where as non-marginal syndesmophytes are more commonly in reactive arthritis and DISH. Marginal syndesmophytes are delicate + symmetric; while non-marginal syndesmophytes are bulky + discontinuous.
