# skfolio.distribution.CopulaRotation ### *class* skfolio.distribution.CopulaRotation(\*values) Enum representing the rotation (in degrees) to apply to a bivariate copula. It follows the standard clockwise convention: - `CopulaRotation.R0` (0°): $(u, v) \mapsto (u, v)$ - `CopulaRotation.R90` (90°): $(u, v) \mapsto (v,\, 1 - u)$ - `CopulaRotation.R180` (180°): $(u, v) \mapsto (1 - u,\, 1 - v)$ - `CopulaRotation.R270` (270°): $(u, v) \mapsto (1 - v,\, u)$ * **Attributes:** **R0** *int* : No rotation (0°). **R90** *int* : 90° rotation. **R180** *int* : 180° rotation. **R270** *int* : 270° rotation.
