The following table summarises the variance explained by PC1 in each PCA run:

Table B.1: PCA diagnostics — variance explained by PC1 (generated from 05_IMPTcalculator.R outputs)

Tip

Table data are read automatically from /impt/pca_scores/PCA_Variance_Table.csv and PCA_Variance_and_Correlations.csv, which are generated by 05_IMPTcalculator.R. Re-run that script to refresh the values after any changes to the input data.
