Hi, After performing a multiple linear regression, I am looking for an R package that can calculate the fraction [a] a partitioning of variation. This fraction measures the proportion of variance of y explained by the explanatory variable x1 (for example) when other variables (x2, x3 ...) are held constant. Thank you in advance for your help -- View this message in context: http://r.789695.n4.nabble.com/fraction-a-a-partitioning-of-variation-tp3652358p3652358.html Sent from the R help mailing list archive at Nabble.com.
