Graphene SMEs: factors influencing product introductions.

Source Web mining analysis of 65 graphene small and medium-sized enterprises (SMEs) in study data set. Results of a binary logistic regression where columns are dependent variables and rows are independent variables (predictors). Cells show the signs of the corresponding coefficient. Significance levels of 90 % or over are denoted with a star (*). For detailed reporting of results, see Appendix Table 5
