Date Model — EventDate-class • kairos

An S4 class to store the event and accumulation times of archaeological assemblages.

Slots

dates: A length-\(m\) numeric vector of dates expressed in rata die.
model: A multiple linear model: the Gaussian multiple linear regression model fitted for event date estimation and prediction.
keep: An integer vector giving the subscripts of the CA components to keep.

Note

Dates are internally stored as rata die. This class inherits from dimensio::CA.

time(x): Extract dates of assemblages.
coef(x): Extract model coefficients.
fitted(x): Extract model fitted values.
