Nonparametric classes of weight functions to model publication bias
用于出版偏差建模的非参数权重函数类
This paper addresses the use of weight functions to model publication bias in meta-analysis. Since publication bias is hard to gauge, a nonparametric ε-contamination class of weight functions is introduced. Sensitivity of conclusions to the specification of the weight function is explored by examining the range of results for the entire ε-contamination class. First, lower bounds are found on the coverage of confidence intervals. If little publication bias is suspected,…
