For most people (maybe everyone?), the PDF is an easier way to visualize the shape of a distribution. But the nice thing about the CDF is that there's no need to look up probabilities for each x-value individually: all of the x-values in the distribution and the associa...
Let x be a random variable with pdf f(x) = x^2/3, -1 is less than x is less than 2, 0, otherwise Find the expected value and variance of g(x) = 3 - 4x Let f(x) = 1/2, -1 lessthanorequalto x lessthanorequal...

Completely new integrated reporting now lets you edit and view reports in Volume Graphics applications exactly as they will appear in the PDF, customize them, automate their creation, and store them directly in your .vgl project. The new integrated reporting function is a fast way to create pres...
In fact, SE is the standard deviation of the fitted parameter obtained from the nonlinear regression. There is no difference between SE and SD when we talk about fitted parameters in the curve fitting. Keywords:SE, SD, parameter, nonlinear curve fit, standard error, standard deviation...
What is the probability that x will take on a value between 21 and 25? X is a continuous uniform (-5, 5) random variable. (a) What is the PDF f_X(x)? (b) What is the CDF F_X (x)? (c) What is E[X]? (d) What is E[X...
In many practical situations, we need to select one of the two alternatives, and we do not know the exact form of the user’s utility function—e.g., we only know that it is increasing. In this case, stochastic dominance result says that if the cumulative distribution function (cdf) ...
