rho |
A length-one numeric vector of zero-inflated parameter in [0,1). |
lambda |
A length-one positive numeric vector of mean. |
anss.target |
A predetermined in-control ANSS/ARL (≤50000L), default is 370.4. |
refv |
A reference value of CUSUM statistic. |
c.zero |
An initial state of CUSUM statistic (default is 0). |
maxndec |
The maximum number of decimal places
of |
maxnumsubI |
The maximum number of sub-intervals in [100,6000] to be used in applying the Markov chain approach. |
