Statistical routines for ndarray
**Description** So that crates using this crate don't have to add it explicitly to their `Cargo.toml`, it would be convenient to have this crate `pub use` things like `noisy_float::types::N64` since...
There exists a method for weighted standard deviation, [weighted_std](https://docs.rs/ndarray-stats/latest/ndarray_stats/trait.SummaryStatisticsExt.html#tymethod.weighted_std), but I can't find one for regular unweighted standard deviation. Is there a reason for this?
**Description** `quantile_mut` can fail with the error message: ``` thread 'main' has overflowed its stack fatal runtime error: stack overflow ``` **Version Information** - `ndarray`: 0.15.4 - `ndarray-stats`: 0.5.0 -...
I just had a situation where I wanted to convert from a covariance matrix to a correlation matrix. It would be neat if we could do that with one function...
The docs for the [correlation methods](https://docs.rs/ndarray-stats/0.5.0/ndarray_stats/trait.CorrelationExt.html#tymethod.cov) say: > Let (r, o) be the shape of M: > * r is the number of random variables; > * o is the...
This is a dual pivot 3-way quick sort which is less likely to run into worst cases which can end in stack overflows for large arrays. The previous single pivot...
Some functions like `mean` are implemented in `ndarray` ([here](https://docs.rs/ndarray/0.13.1/ndarray/struct.ArrayBase.html#method.mean)) and `ndarray-stats` ([here](https://docs.rs/ndarray-stats/0.3.0/ndarray_stats/trait.SummaryStatisticsExt.html#tymethod.mean)). When using `SummaryStatisticsExt`, the function `mean` exists two times, which is not a problem but confusing as one...
Rust 1.49 adds a [`select_nth_unstable`](https://doc.rust-lang.org/stable/std/primitive.slice.html#method.select_nth_unstable) method to slices which is very similar to [`get_from_sorted_mut`](https://docs.rs/ndarray-stats/0.4.0/ndarray_stats/trait.Sort1dExt.html#tymethod.get_from_sorted_mut), except that it returns a mutable reference to the element and additionally returns slices for the...
