SUMMARY

The relationship between the Probability Density Function (PDF) and Cumulative Distribution Function (CDF) of order statistics is defined similarly to that of any PDF and CDF. Specifically, the CDF of a random variable X, denoted as F_X(x), is calculated using the integral of its PDF, f_X(t), from negative infinity to x. This relationship holds true universally for order statistics, confirming the established mathematical principles governing probability distributions.

Hello,

Is the relation between the PDF and CDF of order statistics is as any PDF and CDF. i.e.:

F_X(x)=\int_{-\infty}^{x}f_X(t)\,dt

Yes; that's a general definition.
