This dataset is a collection of emissions data during extrusion processes used to support regression modeling research. The data were collected from various academic publications and patents. Since the case study involving the data was for demonstrative purposes, the dataset involves some approximations to complete all data fields. Users are encouraged to visit the associated journal article and individual sources to better understand if any parts or all of the data are fit for purpose. This dataset is associated with the following publication: Meyer, D.E., R.L. Smith, E. Lanphear, S. Takkellapati, J.D. Chea, G.J. Ruiz-Mercado, M.A. Gonzalez, and W.M. Barrett.
