    for continuous random variable is pdf and cdf will be same ...confused in that .Kindly reply sir ..

    • @confidencematrix
      @confidencematrix  Před 3 lety +1

      The integration limit is very small for pdf (dx) whereas for cdf, the integration limit is from lower limit to upper limit.

    @priyanshimundhra2108 Před 3 lety +1

    what exactly is dx in CDF of continous random variable?

    • @confidencematrix
      @confidencematrix  Před 3 lety +1

      For continuous random variable unlike discrete, we have to integrate because the points of addition are infinite and cannot be added hence dx there represents the distance between 2 points and is infinitely small. :-)

    • @confidencematrix

      No. CDF is cumulative and PDF is a density function at a point (for a continuous variable a very small invlterval delta).
