pulplignin: Pulp lignin content

Description

Pulp quality by lignin content remaining

Format

A data frame with 301 observations on the following 23 variables.

Details

Pulp quality is measured by the lignin content remaining in the pulp: the Kappa number. This data set is used to understand which variables in the process influence the Kappa number, and if it can be predicted accurately enough for an inferential sensor application. Variables with a number at the end have been lagged by that number of hours to line up the data.
