The 697 variants clustered in 423 loci were enriched for genes, pathways and tissue types known to be involved in growth and together implicated genes and pathways not highlighted in earlier efforts, such as signaling by fibroblast growth factors, WNT/β-catenin and chondroitin sulfate–related ...
A low R-squared suggests that the fund's performance is driven by factors other than the benchmark's movements. Important The formula to find R2is to divide the unexplained variance (the sum of the squares of residuals) by the total variance (the total sum of squares). Then, subtract thi...
