4.3 Continuous random variables: Probability density functions

http://www.facweb.iitkgp.ac.in/~baidurya/dissemination/Chapter%204%20random%20variables.pdf SpletA random variable can be either discreet, or continuous. A random variable is governed by its probability laws. If a quantity varies randomly with time, we model it as a stochastic process. A stochastic process can be viewed as a family of random variables. If a quantity varies randomly in space, we model it as a random field, which is the breathable satin fabric

SpletYes, this PDF is a valid density function. A random variable is considered to be continuous if its cumulative distribution function (CDF) is everywhere continuous. There is no other requirement; for example we don't require the density to be continuous. Think of the uniform [ 0, 1] distribution. It is a continuous RV since its CDF.

SpletRemember that for joint discrete random variables, the process of “marginalizing” one of the variables just means to sum over it. For continuous random variables, we have the same process, just replace a sum with an integral. So, to get the pdf for Xor the pdf for Y from the joint pdf f(x;y), we just integrate out the other variable: f X(x ... SpletBy definition 1 and 2 I meant the discrete and continuous definitions for pdf respectively. Discrete random variables have probability mass functions. Continuous random …
