If there are X and Y two random variables. The pdf of Y is f(y), and conditional pdf of X is f(x|y). I want to find the marginal CDF of X, the F(x). Is this correct?(adsbygoogle = window.adsbygoogle || []).push({});

[itex]F(x)=\int^{F(x|y)}_{-\infty}f(y)dy[/itex]

[itex] \dfrac{d}{dx}\int^{F(x|y)}_{-\infty}f(y)dy=\int^{\infty}_{-\infty}f(x|y)f(y)dy=f(x)[/itex]?
