Documentation
Outliers from sample data, calculated using the boxplot technique.
Constructors
| Outliers | |
Fields
| |
data OutlierEffect #
A description of the extent to which outliers in the sample data affect the sample mean and standard deviation.
Constructors
| Unaffected | Less than 1% effect. |
| Slight | Between 1% and 10%. |
| Moderate | Between 10% and 50%. |
| Severe | Above 50% (i.e. measurements are useless). |
Instances
data OutlierVariance #
Analysis of the extent to which outliers in a sample affect its standard deviation (and to some extent, its mean).
Constructors
| OutlierVariance | |
Fields
| |
Instances
Report of a sample analysis.
data SampleAnalysis #
Result of a bootstrap analysis of a non-parametric sample.
Constructors
| SampleAnalysis | |
Fields
| |
Instances
Perform an analysis of a measurement.
Arguments
| :: Double | Value to multiply by. |
| -> SampleAnalysis | |
| -> SampleAnalysis |
Multiply the Estimates in an analysis by the given value, using
scale.
analyseBenchmark :: String -> Vector Measured -> Gauge Report #
Analyse a single benchmark.
Display the mean of a Sample, and characterise the outliers
present in the sample.
countOutliers :: Outliers -> Int64 #
Count the total number of outliers in a sample.
classifyOutliers :: Sample -> Outliers #
Classify outliers in a data set, using the boxplot technique.
noteOutliers :: Outliers -> Gauge () #
Display a report of the Outliers present in a Sample.
Arguments
| :: Estimate ConfInt Double | Bootstrap estimate of sample mean. |
| -> Estimate ConfInt Double | Bootstrap estimate of sample standard deviation. |
| -> Double | Number of original iterations. |
| -> OutlierVariance |
Compute the extent to which outliers in the sample data affect the sample mean and standard deviation.
Arguments
| :: GenIO | |
| -> [String] | Predictor names. |
| -> String | Responder name. |
| -> Vector Measured | |
| -> Gauge (Either String Regression) |
Regress the given predictors against the responder.
Errors may be returned under various circumstances, such as invalid names or lack of needed data.
See olsRegress for details of the regression performed.
benchmark' :: Benchmarkable -> IO () #
Run a benchmark interactively and analyse its performanc.
benchmarkWith' :: Config -> Benchmarkable -> IO () #
Run a benchmark interactively and analyse its performance.
