what is used to interpret standard and residual values when is the appropriate to use standard error versus residual scale in r? when is se.fit used for regression in r definition of standard error and residual scale in r what is the difference between the standard error and the residual scale? what are the standard deviations in r in standard error what is the standard error of the predicted mean? what is sefit versus residual scale what is standard error vs. residual scale in r what is the difference between standard error and residual scale in r what is standard error in r vs residual scale what is standard errors versus residuals in r what is sefit vs residual scale in r r standard error and residual scale what is standard error of the predicted mean in regression what is the difference between standard error and residual scale in r how to interpret expected mean in r what is mean r regression vs standard error what is vs residual in r what is meant by standard error and residual scale in r
