EM.mixture {GGMridge} | R Documentation |
Estimation of the mixture distribution using EM algorithm
Description
Estimation of the parameters, null proportion, and degrees of freedom of the exact null density in the mixture distribution.
Usage
EM.mixture(p, eta0, df, tol)
Arguments
p |
A numeric vector representing partial correlation coefficients. |
eta0 |
An initial value for the null proportion; 1-eta0 is the non-null proportion. |
df |
An initial value for the degrees of freedom of the exact null density. |
tol |
The tolerance level for convergence. |
Value
A list object containing
df |
Estimated degrees of freedom of the null density. |
eta0 |
Estimated null proportion. |
iter |
The number of iterations required to reach convergence. |
