egress osgâm Fr.: émersion The reappearance of a celestial body after an eclipse, an occultation, or a transit; same as emersion. → ingress. From L. egressus, from egredi "to go out," from → ex- "out" + -gredi, comb. form of gradi "to walk, go, step;" from PIE *ghredh- (cf. Lith. gridiju "to go, wander," O.C.S. gredo "to come"). Osgâm "going out," from os- "out," → ex-, + gâm "step, pace," Mid.Pers. gâm, O.Pers. gam- "to come; to go," Av. gam- "to come; to go," jamaiti "goes," Mod.Pers. âmadan "to come," Skt. gamati "goes," Gk. bainein "to go, walk, step," L. venire "to come," Tocharian A käm- "to come," O.H.G. queman "to come," E. come; PIE root *gwem- "to go, come." |
linear regression vâyâzi-ye xatti Fr.: regression linéaire In statistics, a regression method that establishes a linear relationship between two random variables. → linear; → regression. |
nodal regression pasraft-e gerehi Fr.: regression nodale For a ring inclined to the planet's equator, the points at which the ring crosses the equator (nodes) slowly move around the planet (regress) in a direction opposite to that of the ring's orbital motion. (Ellis et al., 2007, Planetary Ring Systems, Springer). → nodal; → regression. |
regression 1) pasraft (#); 2) vâyâzi (#), vâyâzeš (#) Fr.: régression 1) Astro.: → retrograde motion. From L. regression-, from regress-, stem of regredi "to go back," from → re- "back" + gradi "to step, walk." 1) → retrograde. |
regression analysis anâlas-e vâyâzeš Fr.: analyse de régression A statistical technique used to determine the values of parameters for a function that best fits a given set of data. → regression, → analysis. |
regression coefficient hamgar-e vâyâzeš (#) Fr.: coefficient de régression The slope of the straight line that most closely relates two correlated variables. → regression, → coefficient. |
regression curve xam-e vâyâzeš Fr.: courbe de régression A curve representing a non-linear relationship between two or more → variables. → regression, → curve. |
regression equation hamugeš-e vâyâzeš Fr.: équation de régression A mathematical expression that describes the relationship between two or more variables. It indicates the nature of the relationship and, in particular, the extent to which one can predict some variables by knowing others. → regression, → equation. |
regression function karyâ-ye vâyâzeš Fr.: fonction de régression A mathematical function that describes the relationship between two or more variables in a set of data. → regression, → function. |
regression line xatt-e vâyâzeš Fr.: droite de régression The curve representing a → linear regression. It is a line drawn through a set of data that summarizes the relationship between the → variables being studied. → regression, → line. |
regression of the nodes pasraft-e gerehhâ , ~ gowzahrhâ Fr.: régression des noeuds The slow motion of the → nodes of the Moon's orbit in the opposite direction to the Moon's movement. This westward motion, caused by perturbations of other bodies, mainly the Earth and Sun, has a rate of 19.35 degrees per year, making one rotation in 18.6 years. → regression; → node. |
