msmbuilder.MSMLib.estimate_rate_matrix(count_matrix, assignments)[source]

MLE Rate Matrix given transition counts and dwell times

Parameters:

count_matrix : sparse or dense matrix

transition counts

assignments : ndarray

2D assignments array used to compute average dwell times

Returns:

K : csr_matrix

Rate matrix

Notes

The correct likelihood function to use for estimating the rate matrix when the data is sampled at a discrete frequency is open for debate. This likelihood function doesn’t take into account the error in the lifetime estimates from the discrete sampling. Other methods are currently under development (RTM 6/27)
