It’s a little harder to get predictions to a matrix using lapply. In this case, you could use predict within the function, then pass the list to do.call(rbind,mod.list). Because the sample is not the entire population, the sample does not completely represent the population. That’s why there are standard deviations, standard errors, and confidence intervals with all statistics. If we took another sample, it would be slightly different from the original sample and would have slightly different statistics.

Note that, because of the definition of the sample mean, the sum of the residuals within a random sample is necessarily zero, and thus the residuals are necessarily not independent. The statistical errors, on the other hand, are independent, and their sum within the random sample is … So whenever you see a <-in R code, know that it just works like a = but in both directions.
