The Hosmer–Lemeshow test is a statistical test for goodness of fit and calibration for logistic regression models. It is used frequently in risk prediction models. The test assesses whether or not the observed event rates match expected event rates in subgroups of the model population. The Hosmer–Lemeshow test specifically identifies ...
Specific modulus is a materials property consisting of the elastic modulus per mass density of a material. It is also known as the stiffness to weight ratio or specific stiffness. High specific modulus materials find wide application in aerospace applications where minimum structural weight is required. The dimensional analysis yields units of ...

The human genome contains an estimate 18 [100] to 60 [101] genes with no identifiable homologs outside humans. Orphan genes arise primarily from either de novo emergence from previously non-coding sequence , or gene duplication followed by such rapid sequence change that the original relationship becomes undetectable.

There is a significant Calvinist minority (11.6% of the population) and smaller Lutheran (2.2%), Orthodox (0.1%) and Jewish (0.1%) minorities. However, these census figures are representative of religious affiliation rather than attendance; around 12% of Hungarians attend religious services more than least once a week and around 50% more than ...
