The coefficients will then automatically be the standardized "beta"-coefficients (i.e. coefficients in terms of standard deviations). For instance, lm (scale (your.y) ~ scale (your.x), data=your.Data) will give you the standardized coefficient. taking luggage on the lufthansa

The easiest way to compute clustered standard errors in R is to use the modified summary function. lm.object <- lm (y ~ x, data = data) summary (lm.object, cluster=c ("c")) There's an excellent post on clustering within the lm framework. The site also provides the modified summary function for both one- and two-way clustering.
