updateSigSolo {EDISON} | R Documentation |
Sample new values for sigma squared.
Description
This function samples new values for the sigma squared variances, given the current network structure. A univariate distribution is assumed.
Usage
updateSigSolo(X, Y, E, Sall, Ball, Sig2, Mphase, alphad2, betad2, v0, gamma0)
Arguments
X |
Input response data. |
Y |
Input target data. |
E |
Changepoints. |
Sall |
Network structure. |
Ball |
Regression coefficients. |
Sig2 |
Current sigma squared. |
Mphase |
Segment position. |
alphad2 |
Gamma prior hyperparameter. |
betad2 |
Gamma prior hyperparameter. |
v0 |
Inverse gamma prior hyperparameter. |
gamma0 |
Inverse gamma prior hyperparameter. |
Value
Returns the new samples sigma squared values.
