For continuous random variables well define probability density function (PDF) and cumulative distribution function (CDF), see how they are linked and how sampling from random variable may be used to approximate its PDF. On the probability space ( A, F A, P A) we may deР В РЎвЂ”Р вЂ™Р’В¬Р В РЎвЂњne the RV y = x| A with CDF F y ( Р В РЎвЂєР вЂ™Р’В±) = F x | A( Р В РЎвЂєР вЂ™Р’В±| A). This week well study continuous random variables that constitute important data type in statistics and data analysis. Consequently, all remarks and properties regarding a CDF, PMF, and PDF are also valid for the corresponding conditional entities. Recall the discussion in Section 1.8 that a probability space ( A, F A, P A) can be deР В РЎвЂ”Р вЂ™Р’В¬Р В РЎвЂњned such that all conditional probabilities (given event A) on ( S, F, P ) may be computed as unconditional probabilities on ( A, F A, P A).

If x is a discrete RV and P ( A) = 0, from (2.69) we have Domain of the probability density function - Change of variables formula. Note that the conditional CDF F x | A is indeed a CDF in its own right i.e., F x | A is monotone nondecreasing, right-continuous, F x | A(Р В Р вЂ Р Р†РІР‚С™Р’В¬Р Р†Р вЂљРІвЂћСћР В Р вЂ Р Р†РІР‚С™Р’В¬Р РЋРІР‚С”| A) = 0, and F x | A(Р В Р вЂ Р Р†РІР‚С™Р’В¬Р РЋРІР‚С”| A) = 1. Similarly, if x is a continuous RV, we deР В РЎвЂ”Р вЂ™Р’В¬Р В РЎвЂњne the conditional PDF x, given event If x is a discrete RV, we deР В РЎвЂ”Р вЂ™Р’В¬Р В РЎвЂњne the conditional PMF for the RV x, given event A, by If P (A ) = 0 we deР В РЎвЂ”Р вЂ™Р’В¬Р В РЎвЂњne F x | A to be any valid CDF.
