A contingency table, having the same number of rows as columns, in which the definitions of the row and column categories are essentially the same, but differ, for example, by referring to different time points. With the cell (see contingency table) probability denoted by pjk, and parameters relating to rows, columns, diagonals, and individual cells by rj, ck, dl, and mjk, respectively, specialist models include:
- radiation pressure
- radiation resistance
- radiation sickness
- radiation temperature
- radiation tracks
- radiation units
- radiative capture
- radiative collision
- radiative equilibrium
- radiative forcing
- radiative recombination
- radiative transfer
- radiative zone
- radiatus
- radiaxial
- radical
- radical axis
- radical geography
- radical interpretation
- radical ion
- radical sign
- radical translation
- radicand
- radicle
- radio
