How to correct my error message
Hi, a is of length 60. b is of length 60. z is of length 57. What do you expect to have happen when you create y_model ? What happens to those other 3 observations?

How to correct my error message
Dear R-experts, Here below my R code. The warning message is not a problem to me but there is an error message more problematic. I understand the error message but I don't know if it is possible to correct the error and if yes, how to correct it. Many thanks. n <- 60 b <- runif(n, 0, 5) a <- runif(n, 0, 5) z <- rnorm(n*0.95,2,3) + rnorm(n*0.05,2,9) y_model <- 0.1 * b - 0.5 *
