In spcadjust: Functions for Calibrating Control Charts

Data Model for Binary Responses using a Logarithmic Model and observed minus expected updates.

1	SPCModellogregOE(formula, Delta = 0)

`formula`	The formula of the model.
`Delta`	Half of this value will be subtracted for every update.

n <- 1000

xbeta <- -1+Xlogreg$x1*100+Xlogreg$x2+Xlogreg$x3
Xlogreg$y <- rbinom(n,1,exp(xbeta)/(1+exp(xbeta)))
