help on retrieving output from by( ) for regression
Look more carefully at ?lm at the See Also section ... X <- rnorm(30) Y <- rnorm(30) lm(Y~X) summary(lm(Y~X)) Best, Matthias
Hi all I used a function
qtrregr <- by(AB, AB$qtr, function(AB) lm(AB$X~AB$Y))
objective is to run a regression on quartery subsets in the data set AB, having variables X and Y, grouped by variable qtr. Now i retrieved the output using qtrregr, however it only showed the coefficients (intercept and B) with out significant levels and residuals for each qtr. Can some on help me on how can retrieve the detailed regression output. rgds snvk
