negative skewness
  کژالی ِ ناییدار   
kažâli-ye nâyidâr

Fr.: asymétrie négative   

Of a distribution function, a skewness in which the left tail (tail at small end of the distribution) is more pronounced that the right tail (tail at the large end of the distribution). → positive skewness.

negative; → skewness.

positive skewness
  کژالی ِ داهیدار   
kažâli-ye dâhidâr

Fr.: asymétrie positive   

Of a distribution function, a skewness in which the right tail (tail at the large end of the distribution) is more pronounced than the left tail (tail at small end of the distribution). → negative skewness.

positive; → skewness.

skew
  کژال   
kažâl

Fr.: distordu   

General: Having an oblique direction or position; being in a slanted or unsymmetrical position.
Geometry: Two or more lines that are not parallel and do not intersect.
Statistics: Having → skewness.

From Old North French eskiuer "to shy away from, avoid," O.Fr. eschiver (Fr. esquiver "to shirk, dodge") "to eschew, keep away from;" related to shy.

Kažâl, from kaž "crooked, bent, being aside" (cf. Skt. kubja- "hump-backed, crooked," Pali kujja- "bent," L. gibbus "hump, hunch," Lith. kupra "hump") + -âl, → -al.

skew-symmetric tensor
  تانسور ِ پاد-همامون   
tânsor-e pâdhamâmun

Fr.: tenseur antisymétrique   

A tensor that is the negative of its → transpose. For example, a second-order covariant tensor Ajk if its components satisfy the equality: Ajk = - Akj. Also called antisymmetric tensor.

skew; → symmetric; → tensor.

Tânsor, → tensor; pâd-, → anti-; hamâmun, → symmetric.

skewness
  کژالی   
kažâli

Fr.: degré d'asymétrie   

A measure of the degree of asymmetry of a distribution. If the left tail (tail at small end of the distribution) is more pronounced that the right tail (tail at the large end of the distribution), the function is said to have → negative skewness. If the reverse is true, it has → positive skewness. If the two are equal, it has → zero skewness.

Noun from → skew + → -ness.
