bpr_EM
implements the EM algorithm for performing clustering on DNA
methylation profiles, where the observation model is the Binomial
distributed Probit Regression function, bpr_likelihood
.
1 2 3 4 |
x |
A list of elements of length N, where each element is an L x 3 matrix of observations, where 1st column contains the locations. The 2nd and 3rd columns contain the total trials and number of successes at the corresponding locations, repsectively. |
K |
Integer denoting the number of clusters K. |
pi_k |
Vector of length K, denoting the mixing proportions. |
w |
A MxK matrix, where each column contains the basis function coefficients for the corresponding cluster. |
basis |
A 'basis' object. E.g. see |
em_max_iter |
Integer denoting the maximum number of EM iterations. |
epsilon_conv |
Numeric denoting the convergence parameter for EM. |
opt_method |
The optimization method to be used. See
|
opt_itnmax |
Optional argument giving the maximum number of iterations
for the corresponding method. See |
is_parallel |
Logical, indicating if code should be run in parallel. |
no_cores |
Number of cores to be used, default is max_no_cores - 1. |
is_verbose |
Logical, print results during EM iterations |
