On the asymptotic distribution for Peto's combined test for carcinogenicity assays under equal and unequal censoring
相同与不同删失下 Peto 致癌性联合检验的渐近分布
Peto et al. (1980) proposed a combined test statistic for carcinogenicity studies in a pooled analysis of incidental and fatal tumours. For the analysis of the incidental tumours one needs to divide the time span of the study into subintervals. Rather than using the data‐driven method approach to create these intervals as was suggested by Peto et al. (1980), in practical applications one uses a fixed number of prespecified intervals. For this method we derive the asymptotic…
