statsmodels.tsa.statespace.tools.validate_vector_shape(name, shape, nrows, nobs) [source]

Validate the shape of a possibly time-varying vector, or raise an exception

Parameters:	name : str The name of the vector being validated (used in exception messages) shape : array_like The shape of the vector to be validated. May be of size 1 or (if the vector is time-varying) 2. nrows : int The expected number of rows (elements of the vector). nobs : int The number of observations (used to validate the last dimension of a time-varying vector)
Raises:	ValueError If the vector is not of the desired shape.
