Recently, producing high-precision and high-quality steel products becomes the major aim of the large-scale iron and steel enterprises. Because of the internal multiplex components of products and complex changes in the production process, it is too difficult to achieve precise control in hot rolling production process. In this paper, radial basis function neural network is used to complete performance...
This paper proposes an improved meta-analysis for truncated data to decrease the bias from file drawer problem for meta-analysis. It shows the construction of confidence intervals and test after parameters estimate approached by maximum likelihood estimate with Newton-Raphson iteration, or by way of bootstrap method or jackknife method which beyond the tradition method under the supposition that parameters...
