  • dispersiooni arvutamisel kasutatav suurus
  • dispersiooni arvutamisel kasutatav sõltumatute tulemuste (mõõdiste) arvust ühe võrra väiksem arv
  • divisor used in the calculation of variance
  • divisor used in the calculation of variance, one less than the number of independent results
  • (primary mathematical model) number of independent parametrs required to fully describe a particular primary mathematical model
vabadusastmete arv
Usage examples
  • Vabadusastmete arv on üldiselt mõõdiste arv summas, millest on lahutatud piirangute arv.
Good to know
  • Vabadusastmete arv tasapinnal asuval punktil on kaks, ehk selle kaks koordinaati, kuid tasapinnal asuval objektil võivad olla selle orientatsiooniga seotud veel täiendavad vabadusastmed.

degrees of freedom preferred
Usage examples
  • In general, degrees of freedom is the number of terms in a sum minus the number of constraints on the terms of the sum.
Good to know
  • For example, a point in the plane has two degrees of freedom for translation: its two coordinates; a non-infinitesimal object on the plane might have additional degrees of freedoms related to its orientation.In general, the number of terms in a sum minus the number of constraints on the terms of the sum.
