Function compute

compute(mean: number, standardDeviation: number): (value: number) => number
Returns a function that computes zscore-based normalisation.
```
// Calculate necessary components
const m = mean(data);
const s = standardDeviation(data);

// Get the function
const fn = compute(m, s);

// Use it
fn(10); // Yields the normalised value
```
It can be used to normalise a whole array
```
const normalised = someData.map(fn);
```
If you want to calculate for a whole array, use array.
Parameters
- mean: number
  Mean of data
- standardDeviation: number
  Standard deviation of data
Returns (value: number) => number
