i run ols model using lm() in r , replace standard errors in model. in following example, replace each standard error "2": set.seed(123) x <- rnorm(100) y <- rnorm(100) mod <- lm(y ~x) ses <- c(2,2) coef(summary(mod))[,2] <- ses sqrt(diag(vcov(mod))) <- ses any thoughts on how this? thanks. those assignments not going succeed. coef , sqrt , vcov not going pass values "upstream". this: > false.summ <- coef(summary(mod)) > false.sqrt.vcov <- sqrt(diag(vcov(mod))) > false.summ estimate std. error t value pr(>|t|) (intercept) -0.10280305 0.09755118 -1.0538371 0.2945488 x -0.05247161 0.10687862 -0.4909459 0.6245623 > false.summ[ , 2] <- ses > false.sqrt.vcov (intercept) x 0.09755118 0.10687862 > false.sqrt.vcov <- ses you modify summary-object @ least coef -matrix, there no "vcov" element in summary despite fact vcov return value. > sum...
