A confidence interval for the mean
meanConfInt( vector = NULL, mean = NULL, sd = NULL, n = NULL, se = NULL, conf.level = 0.95 ) # S3 method for meanConfInt print(x, digits = 2, ...)
| vector | A vector with raw data points - either specify this or a mean and then either an sd and n or an se. |
|---|---|
| mean | A mean. |
| sd, n | A standard deviation and sample size; can be specified to compute the standard error. |
| se | The standard error (cna be specified instead of |
| conf.level | The confidence level of the interval. |
| x, digits, ... | Respectively the object to print, the number of digits to
round to, and any additonal arguments to pass on to the |
And object with elements input, intermediate, and output,
where output holds the result in list ci.
