| Abstract: | Based on the analysis of various variogram models in geostatistics,we put forward the uniform parameter estimated methods of linearizing,and primely simplify the problem of parameter estimation.It modularized software design,improves the versatility of the algorithm.We use the linear programming method of lag behind the inverse weighted after linearizing model for automatic fitting,give numerical experiments and make a summary.The results show that various theoretical models have results of data fitting. |
