Auxiliary function for zim fitting. Typically only used internally by
zim.fit, but may be used to construct a control argument for either function.
zim.control(dist = c("zip", "zinb"), method = c("EM-NR", "EM-FS"), type = c("solve", "ginv"), robust = FALSE, trace = FALSE, start = NULL, minit = 10, maxit = 10000, epsilon = 1e-08)
| dist | count model family. |
|---|---|
| method | algorithm for parameter estimation. |
| type | type of matrix inverse. |
| robust | logical; if TRUE, robust standard errors will be calculated. |
| trace | logical; if TRUE, display iteration history. |
| start | initial parameter values. |
| minit | minimum number of iterations. |
| maxit | maximum number of iterations. |
| epsilon | positive convergence tolerance. |
