Discussion on determination of probability distribution parameters using weighting function arithmetic
Ma Xiu · Journal of Hydraulic Engineering · 2001
A numerical integral approach arithmetic using weighting function is proposed.It can solve the coefficients of sampling variation and skewness simultaneously.The solution procedures of exponential and variation single weighting functions are introduced in detail.The numerical integral arithmetic of double weighting function is also improved.An example solved by using Mathcad 7\^0 is given for demonstration.The calculation result is compared with those using arithmetic of double weighting function and moment method of numerical integral.
