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

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

Parameters: name (str) – The name of the matrix being validated (used in exception messages) shape (array_like) – The shape of the matrix to be validated. May be of size 2 or (if the matrix is time-varying) 3. nrows (int) – The expected number of rows. ncols (int) – The expected number of columns. nobs (int) – The number of observations (used to validate the last dimension of a time-varying matrix) ValueError – If the matrix is not of the desired shape.
