does rnorm use standard deviation what is the standard deviation for wood does r use the sd for the standard deviation when rnorm is used to calculate a value for a decay tree when to use se as standard deviation in rnorm? what is the difference between se and standard error what is the difference between rnorm and sd which arithmetic function is appropriate for rnorm in rnoorm what is the difference between sd and rnorm what is rnorm used for when to use rnorm instead of sd what is the standard deviation of rnorm what is the value of se for rnorm what is the standard deviation for rnorm what is the sd value for r do i need sd or se what is sd in r r how to calculate density what is standard error in r when using rnorm, is it appropriate to use a sd instead of a standard error?
