%0 Journal Article %T Using the Transformation Method to Evaluate The Probability Density Function of z = x¦Á y¦Â %A Seifedine Kadry %A Khaled Smaily %J The International Journal of Applied Economics and Finance %D 2007 %I Asian Network for Scientific Information %X In this research, our objective is to evaluate the probability density function of z = x¦Áy¦Â, where, x and y are two independent random variables, by using the probabilistic transformation method. The Probabilistic Transformation Methods (PTM) evaluate the Probability Density Function (PDF) of a function by multiplying the input pdf by the Jacobian of the inverse function. A new theorem for two input and one output has been developed. The result of our method is verified by the Monte Carlo simulation. %K Transformation method %K probability %K density %K evaluation %U http://docsdrive.com/pdfs/ansinet/ijaef/2007/105-112.pdf
