The first 3 rows in the table describe a hierarchy of information about the factor analyzed to extract information relevant for the tissue of origins listed in column 1. Namely: the type of analysis, that is joint or separate. Within the separate analysis 3 options are possible i.e. analysis of mRNA only, or miRNA only or proteins only. Finally, the factor analysis model (M) chosen to describe the tissue is noted in row 3, the number indicates the number of factors obtained from the analysis. Finally each cell in the matrix indicate which factor among the ones available in the model better describe each tissue type. In each cell, accuracy (acc.) and p-value related to the ability of the Factor to predict the tissue are reported.
