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

Slots

id

A character string specifying the unique identifier of the corresponding matrix (UUID v4).

counts

A numeric matrix of count data.

level

A length-one numeric vector giving the confidence level.

model

A multiple linear model: the Gaussian multiple linear regression model fitted for event date estimation and prediction.

rows

A four columns numeric matrix giving the predicted event dates for each archaeological assemblage, with the following columns:

date

The event date estimation.

lower

The lower boundary of the confidence interval.

upper

The upper boundary of the confidence interval.

error

lower

The lower boundary of the confidence interval.

upper

The upper boundary of the confidence interval.

error
