This paper considers the estimation of both the intercept term and the slope parameter in a linear ultrastructural model using
direct regression and reverse regression methods. Without assuming the errors to be normally distributed, asymptotic expressions
for the bias and the variance of the estimators are derived and analyzed. The effect of departure of the errors from normality
is also studied. 相似文献

三维地震资料连片的一致性处理技术 总被引:7,自引:1,他引:6
三维地震资料连片处理是一套复杂而精细的数字处理工作。根据各区块三维地震资料的频率、相位、时差、信噪比等的特殊性和差异性,采用叠前能量一致性、相位一致性和振幅一致性处理方法,对能量、振幅、相位等有效地进行一致性补偿和校正,使各区块资料在保持原有品质的前提下,既提高了信噪比和分辨率,又保证了资料整体拼接的一致性。应用该方法处理胜利桩海地区23块共1500km^2三维资料,取得了良好的效果。 相似文献

Potential for large-scale physical transport processes to affect recruitment of Lake Michigan yellow perch (Perca flavescens) was studied by examining the variation in larval distribution, growth rate, and settlement during June–August 1998–2003 using a 3D particle transport model linked with an individual-based bioenergetics growth model. In all years, virtual larvae were released nearshore in southwestern Lake Michigan, a known and important spawning region for yellow perch. For any given year, the same circulation pattern and water temperature either promoted or reduced yellow perch settlement depending on the consumption rates and settlement size chosen in the growth model. Increased consumption increased the number of settled larvae and expanded the total area where larvae settled, whereas increased settlement size reduced the number of settled larvae and reduced the overall settlement area. Interannual variability in circulation patterns and water temperature also resulted in contrasting larval settlement rates, settlement locations, and size of settlement areas between years. Model predictions were most consistent with field observations of age-0 yellow perch from Illinois and Michigan waters when settlement was assumed to occur at 50 mm. Moreover, our model suggests that larvae originating from southwestern Lake Michigan can recruit anywhere within the southern basin and even in the northern basin. Future model improvement will require information on the relative contribution of various sectors to the larval pool, their distribution with reference to the hydrodynamic landscape, the feeding and growth of yellow perch during their pelagic phase, and the size at transition to demersal stage. 相似文献

A modified CIECAM02 colour appearance model, named CIECAM02‐m2, is proposed to enable CIECAM02 to predict the simultaneous contrast effect. The structure of the CIECAM02‐m2 is a development from CIECAM02, and contains two different procedures for modifying the reference white; one is for lightness and the other is for hue. The model was tested using a data set accumulated in this study and the LUTCHI data. The CV values for three colour attributes between predictions and experimental data were used to evaluate the accuracy of the model. The low CV values obtained show the performance of the CIECAM02‐m2 model to predict the simultaneous contrast effect satisfactorily. © 2007 Wiley Periodicals, Inc.
