- Parameters of such models are estimated not with regression analysis but non-linear techniques such as generalized method of moments, maximum likelihood, and indirect inference.
- In probability theory, the "'method of moments "'is a way of proving convergence in distribution by proving convergence of a sequence of moment sequences.
- One alternative is to use as initial values for iteration the values obtained from the method of moments solution for the four parameter case.
- GMM was developed by Lars Peter Hansen in 1982 as a generalization of the method of moments which was introduced by Karl Pearson in 1894.
- There are many ways to estimate the coefficients, such as the ordinary least squares procedure or method of moments ( through Yule Walker equations ).
- Once this has been done, the integral equation can then be solved by a numerical technique appropriate to integral equations such as the method of moments.
- If a closed-form expression is needed, the method of moments can be applied to estimate \ alpha from the sample skew, by inverting the skewness equation.
