No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Abstract Winkelmann and Zimmermann (1993), although available only as a working paper, has initiated a small but persistent literature on underreporting in count data models. Their Poisson-logistic (Pogit) model was initially developed to estimate the determinants of the number of job offers during a given time interval, when the researcher only observes the number of accepted offers. Later Pogit applications can be found in epidemiology, engineering, public health, and criminology, among others. I review some of the recent developments in the literature. I also consider an extension of the original model where the reporting process can be estimated separately from the event generating process due to the availability of a validation dataset.
