pymc.MvStudentTRandomWalk#
- class pymc.MvStudentTRandomWalk(name, *args, **kwargs)[source]#
Multivariate Random Walk with StudentT innovations
- Parameters
- nu: int
degrees of freedom
- mu: tensor_like of float
innovation drift
- scale: tensor_like of float
pos def matrix, innovation covariance matrix
- tau: tensor_like of float
pos def matrix, inverse covariance matrix
- chol: tensor_like of float
Cholesky decomposition of covariance matrix
- lowerbool, default=True
Whether the cholesky fatcor is given as a lower triangular matrix.
- init_dist: distribution
- Unnamed multivariate distribution of the initial value. Unnamed refers to distributions
created with the
.dist()
API.Warning
init_dist will be cloned, rendering them independent of the ones passed as input.
- steps
int
, optional Number of steps in Random Walk (steps > 0). Only needed if shape is not provided.
Notes
Only one of cov, tau or chol is required.
