对 Freedman 无应答案例研究的另一种解释AI 解读

Further analysis of the response–nonresponse data presented by Freedman (1986) shows evidence of a nonresponse bias. Covariates can be useful in comparing respondents with nonrespondents; however, we argue that they were not effective in this case. Follow-up sampling would provide stronger evidence concerning the similarity of the two groups.

经典与现代回归及其应用AI 解读

The author emphasizes applications with examples that illustrate nearly all the techniques discussed. Applications have been selected from physical sciences, engineering, biology, management science and economics. Emphasis is also placed on concepts with a blend between illustrations using real data sets and mathematical and conceptual development. Expanded coverage includes: simultaneous influence, maximum likelihood estimation of parameters, and the plotting of residuals,…

百分位数的同时置信带与判别集合AI 解读

Using the general linear model, y = Xβ+e, where e∼N(0, σ2/): simultaneous confidence bonds are found for the 100 pth percentile, x′β+kpσ, of the normal population with mean x′β and variance σ2 (kp is the 100 pth percentile of the standard normal distribution). The bands are simultaneous in x or in x and p. In the simple linear regression case these bands are used to define simultaneous discrimination sets for any fixed values, yP, of the dependent variable.
