319 results about "Goodness of fit" patented technology

The goodness of fit of a statistical model describes how well it fits a set of observations. Measures of goodness of fit typically summarize the discrepancy between observed values and the values expected under the model in question. Such measures can be used in statistical hypothesis testing, e.g. to test for normality of residuals, to test whether two samples are drawn from identical distributions (see Kolmogorov–Smirnov test), or whether outcome frequencies follow a specified distribution (see Pearson's chi-squared test). In the analysis of variance, one of the components into which the variance is partitioned may be a lack-of-fit sum of squares.

The invention belongs to the radar target detection technology field and relates to a radar target constant false alarm rate detection method. The radar target constant false alarm rate detection method mainly comprises the following steps: 1) the Weibull background distribution is converted to the Location-Scale distribution through the logarithmic transformation; 2) the orderly truncated (or head cut) treatment is carried out to a background sample to suppress the impact of an interference target, a largest unbiased estimator is adopted for estimating the location and the scale parameters; 3) the normalization of samples in a unit to be tested is carried out by using the estimated parameters; 4) the judgment of whether the background distribution is obeyed or not is carried out by utilizing the Anderson-Darling test, if the background distribution is not obeyed, the target is judged to exist, otherwise, no target is judged to exist. The radar target constant false alarm rate detection method utilizes the difference of the distribution characteristics of the target echo and the background clutter, compared with the traditional detection method based on a self-adaptive threshold, the characteristics of the background distribution and the interference target have little impact on the radar target constant false alarm rate detection method, thereby having very strong adaptability to the non-Gaussian environment and the multi-objective interference environment.

Solution-dependent regularization method for quantizing continuous-tone lithography masks

In an electronic design automation technique for optical proximity correction, an optimized mask function that has values other than those allowed for a particular mask type, such as 0 and 1 for a chrome-on-glass binary mask, evolves it to a solution restricted to these values or narrow intervals near them. The technique “regularizes” the solution by mixing in a new cost functional that encourages the mask to assume the desired values. The mixing in may be done over one or more steps or even “quasistatically,” in which the total cost functional and the mask is brought from pure goodness-of-fit to the printed layout for given conditions to pure manufacturability by keeping the total cost functional minimized step-by-step. A goal of this gradual mixing-in is to do thermodynamically optimal work on the mask function to bring it to manufacturable values.
