The log-rank test and Cox’s proportional hazard model can be used to compare survival curves but are limited by strict statistical assumptions. In this study, we introduce a novel, assumption-free method based on a random forest algorithm able to c

There are several established methods for comparing more than two survival curves, namely the scale-rank test or Cox’s proportional hazard model. However, when their statistical assumptions are not met, their results’ validity is affected.In this

Estimates performed particularly using small samples are a priori inaccurate. Furthermore, estimations of m-year survival rates, especially for large m ≫ 0, are inevitable of low precision because they are calculated as fractions with both low nume

When having more initial data than needed, an appropriate selection of a subpopulation from the given dataset, i. e. subsampling, follows, usually intending to ensure all categorical variables’ levels are nearly equally covered and all numerical va

Comparison of two time-event survival curves representing two groups of individuals’ evolution in time is relatively usual in applied biostatistics. Although the log-rank test is the suggested tool how to face the above-mentioned problem, there is

Computerized adaptive testing (CAT) is a modern alternative to classical paper and pencil testing. CAT is based on an automated selection of optimal item corresponding to current estimate of test-taker’s ability, which is in contrast to fixed prede

Associations between geometric features of a human face and facial attractiveness level is important for planning of facial aesthetic surgeries including rhinoplasty, but is complex enough and remains still unclear. Going further, facial attractivene
