# precisionMeasures: Precision measures In superb: Summary Plots with Adjusted Error Bars

## Description

superb comes with a few built-in measures of precisions. All `SE.fct()` functions produces an interval width; all `CI.fct()` produces the lower and upper limits of an interval. See \insertCitehtc14,htc15superb for more. "superbPlot-compatible" precision measures must have these parameters:

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43``` ```SE.mean(x) CI.mean(x, gamma) SE.median(x) CI.median(x, gamma) SE.hmean(x) CI.hmean(x, gamma) SE.gmean(x) CI.gmean(x, gamma) SE.var(x) CI.var(x, gamma) SE.sd(x) CI.sd(x, gamma) SE.MAD(x) CI.MAD(x, gamma) SE.IQR(x) CI.IQR(x, gamma) SE.fisherskew(x) CI.fisherskew(x, gamma) SE.pearsonskew(x) CI.pearsonskew(x, gamma) SE.fisherkurtosis(x) CI.fisherkurtosis(x, gamma) ```

## Arguments

 `x` a vector of numbers, the sample data (mandatory); `gamma` a confidence level for CI (default 0.95).

## Value

a measure of precision (SE) or an interval of precision (CI).

## Examples

 ```1 2 3 4 5 6 7 8``` ```# the confidence interval of the mean for default 95% and 90% confidence level CI.mean( c(1,2,3) ) CI.mean( c(1,2,3), gamma = 0.90) # Standard errors for standard deviation, for MAD and for fisher skew SE.sd( c(1,2,3) ) SE.MAD( c(1,2,3) ) SE.fisherskew( c(1,2,3) ) ```
