            these practices within AM can be tracked over time by   of sample size, model adequacy, model selection,
            a journal or a scientific body by measuring an index of   randomization, and blocking. The repository also includes
            statistical sophistication. Ensuring statistical precision   the R script, which will reproduce the figures and analyses
            is highly critical for AM since it is used to produce parts   in this manuscript.
            for highly regulated industry segments such as aerospace,
            medicine, and similar fields.                      References
