Marginal probability distributions arise from joint probability measures on product spaces. The marginal distributions are the push-forward measures induced by the coordinate projections.

Can I find the marginal distribution by fitting a distribution to the event dimension, rather than integrating over the variables?
I have a 6-dimensional data which I fitted with a 6-dimensional Gaussian mixture model and I would like to obtain the marginal distribution of all 1-dimensional events. However, I find it difficult to perform integration over the irrelevant…

Marginal distribution of a uniform distribution on a unit disk
I am trying to find the marginal pdf of a uniform distribution on a unit disk.
Let $f_{XY}=\frac{1}{\pi}$, where $X^2+Y^2\leq1$
Here's my attempt:
$$f_X(x)=\int^{\sqrt{1-x^2}}_{-\sqrt{1-x^2}}\frac{1}{\pi}dy = \frac{1}{2\sqrt{1-x^2}}$$
But i'm not…

Random Variable Y given X
I have been given a joint probability distribution function and asked to find the marginal probability distributions.
$$f(x,y)=\begin{cases}
λ^2e^{-λy}&0\le x\le y\\
0&\text{otherwise}
\end{cases}$$
how do i compute the marginal distribution of x if…

Marginal and Joint Distribution
Find the marginal probability density function of x.
I found the marginal of y but cannot understand how to find the marginal of x.
Can someone explain how do we approach this problem?
