Calculate the population variance or standard deviation of a vector.
var_pop(x)sd_pop(x)
(Numeric) vector.
The population variance or standard deviation of x
.
Unlike var
, which returns the sample variance,
var_pop()
returns the population variance. sd_pop()
returns the standard deviation based on the population variance.
# NOT RUN {
data(efc)
# sampling variance
var(efc$c12hour, na.rm = TRUE)
# population variance
var_pop(efc$c12hour)
# sampling sd
sd(efc$c12hour, na.rm = TRUE)
# population sd
sd_pop(efc$c12hour)
# }
