WEIBULL_MCMEAN(R1, R2,alpha, beta) = the mean of all the data in R1 plus the average life of the censored data in R2 based on a Weibull distribution with parametersalphaandbeta WEIBULL_MCVAR(R1, R2,alpha, beta, iter) = the variance of all the data in R1 as we...
These data are interval-censored. Owing to the lack of well-known statistical methodology and available software, a common ad hoc approach is to assume that the event occurred at the end (or beginning or midpoint) of each interval, and then apply methods for standard time-to-event data. ...
First, the data are contaminated, meaning that the exclusion restrictions of the IV estimator hold for only a fraction of the sample. Second, we allow for the data to be censored. After relaxing these assumptions point identification is no longer feasible, but we are able to construct sharp ...

Since we have given them a window to think about, there are lots of loans that don't have a decision yet, meaning that they are right censored since the 6 months window hasn't expired yet Having censored data means there are lots of loans that we can't use as ...
Tutorial in biostatistics methods for interval-censored data. In standard time-to-event or survival analysis, occurrence times of the event of interest are observed exactly or are right-censored, meaning that it is on... JC Lindsey,LM Ryan - 《Statistics in Medicine》 被引量: 616发表: 1998...
For the Youden index method, the variability of the objective function estimate in the presence of censored data can be addressed by ap- plying the delta method and by handling the covariance issue as in Antolini and Valsecchi [9]. When methods point to different true cut-points...

In this section, we will present the self-understanding of our subjects. We followed an abductive strategy, where inductive reading and re-reading of the data has made us gradually change what theories and concepts we found most useful. The initial phase of data analysis revealed the uniform pe...
All you “know” is that they got sick, or died, or tested positive, etc. But if you claim that COVID caused this, you just moved from the realm of reality based on experience and data, to the realm of BELIEF where you attribute this to COVID based onwha...
