Dataset and Statistical Analysis of a Central Composite Design for Lignin Solubilization in Aqueous NaOH

In the first sheet, one can visualize the experiments made and their response variable values. The next three sheets have the results of the analysis done with Stat-Ease Software for each of the response variables - density, mass fraction of lignin, and pH. In each sheet, one will find the ANOVA tables, and the models generated with both standardized and original values. Furthermore, values such as the adjusted coefficients of determination, predictive coefficient of determination, and the adequate precision of the models are also available.
