(mt_trans, fl_atol_per_row=1e-05, fl_atol_avg_row=1e-08, fl_sum_to_match=1)[source]¶ Markov conditional transition probability check
- Parameters
- mt_transnumpy.array of shape (N, N)
The AR1 transition matrix, each row is a state, each value in each row is the conditional probability of moving from state i (row) to state j (column)
- fl_atol_per_rowfloat, optional
Tolerance for the difference between 1 and each row sum
- fl_atol_avg_rowfloat, optional
Tolerance for the difference between 1 and average of row sums
- fl_sum_to_matchfloat, optional
This should be 1, unless the function is not used to handle transition matrixes
- Returns
- ——-
- tuple
A tuple of booleans, the first element is if satisfies the overall criteria. Second is if satisifes the per_row condition. Third if satisfies the average criteria.
