This folder contains the material provided as Appendix 5 of deliverable D6 final report of phase 1 of the Characterisation of Feedstocks project: correlation analysis results. The relationships between provenance information (e.g. soil properties, site characteristics, and crop management) and feedstock characteristics were investigated by correlation analysis. Correlation coefficients were investigated in two ways: using the actual numeric values, which gives Correlation Coefficients, or the ranks, which gives Spearman Rank Coefficients. In the latter approach, the values for each of the variables to be related are ordered from the highest to lowest value with the value one assigned to the top ranked site. The rankings of the sites for the variables being related are then compared. In situations where there only a few pairs of values to be related or the relationship deviates from being linear, the Spearman correlation procedure is more appropriate. The data are in sub folders Miscanthus, Poplar_SRF, Spruce_SRF and Willow_SRC. Filenames take the form _[_][_]. Data type can be: correlation_pairwise_rectangle = correlation coefficients from the numeric values spearman_correlation_pairwise_rectangle = Spearman Rank Coefficients number_observations_pairwise_rectangle = Number of observations available to calculate the correlation coefficients. Format is csv or pdf with each data file provided in both formats. CSV format is comma separated variables ASCII data. PDF format shows a view of the table data with colour highlighting to pick out correlations above or below certain thresholds and observation numbers below certain thresholds. PDF format colour shading: Correlation coefficients (r) and their corresponding r-squared (r^2) values : Light orange r >= 0.7 (r^2 >= 49%) Dark orange r > 0.9 (r^2 > 81%) Light purple r < =-0.7 (r^2 >= 49%) Dark purple r <= -0.9 (r^2 > 81%) Number of observations: Pink to red for reduced numbers of observations.
