A well tested and comprehensive Golang statistics library package with no dependencies.
If you have any suggestions, problems or bug reports please [create an issue](https://github.com/montanaflynn/stats/issues) and I'll do my best to accommodate you. In addition simply starring the repo would show your support for the project and be very much appreciated!
A statistics package with many functions missing from the Golang standard library. See the [CHANGELOG.md](https://github.com/montanaflynn/stats/blob/master/CHANGELOG.md) for API changes and tagged releases you can vendor into your projects.
> Statistics are used much like a drunk uses a lamppost: for support, not illumination. **- Vin Scully**
## Installation
@ -11,130 +10,55 @@ If you have any suggestions, problems or bug reports please [create an issue](ht
go get github.com/montanaflynn/stats
```
## Example Usage
**Protip:** `go get -u github.com/montanaflynn/stats` updates stats to the latest version.
All the functions can be seen in [examples/main.go](https://github.com/montanaflynn/stats/blob/master/examples/main.go) but here's a little taste:
```go
// start with some source data to use
data := []float64{1.0, 2.1, 3.2, 4.823, 4.1, 5.8}
// you could also use different types like this
// data := stats.LoadRawData([]int{1, 2, 3, 4, 5})
// data := stats.LoadRawData([]interface{}{1.1, "2", 3})
// etc...
median, _ := stats.Median(data)
fmt.Println(median) // 3.65
roundedMedian, _ := stats.Round(median, 0)
fmt.Println(roundedMedian) // 4
```
## Documentation
## Usage
The [entire API documentation](http://godoc.org/github.com/montanaflynn/stats) is available on GoDoc.org
You can view docs offline with the following commands:
```
# Command line
godoc ./
godoc ./ Median
godoc ./ Float64Data
# Local website
godoc -http=:4444
open http://localhost:4444/pkg/github.com/montanaflynn/stats/
```
The exported API is as follows:

To make things as seamless as possible please also consider the following steps:
- Update `examples/main.go` with a simple example of the new feature
- Update `README.md` documentation section with any new exported API
- Keep 100% code coverage (you can check with `make coverage`)
- Squash commits into single units of work with `git rebase -i new-feature`
- Update `README.md` to include new public types or functions in the documentation section.
- Update `examples/main.go` with a simple example of the new feature.
- Keep 100% code coverage (you can check with `make coverage`).
- Run [`gometalinter`](https://github.com/alecthomas/gometalinter) and make your code pass.
- Squash needless commits into single units of work with `git rebase -i new-feature`.
#### Makefile
I've included a [Makefile](https://github.com/montanaflynn/stats/blob/master/Makefile) that has a lot of helper targets for common actions such as linting, testing, code coverage reporting and more.
**Protip:** `watch -n 1 make check` will continuously format and test your code.
