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

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)

Raises:

ValueError – If the matrix is not of the desired shape.
