Lines 219 to 220 in 2ce755a

	for i in range(self.n_ele):
	estimation[:, t] += estimation_table[:, i]*beta[i] # C*(x) Eq 18

is IMHO mathematically equivalent with:

estimation[:, t] = np.dot(estimation_table, beta)

which should be faster.

However, the obtained results may differ due to numerical issues.
