Function moodTest

moodTest(x: Sample, y: Sample, options?: MoodTestOptions): HTest
Mood's two-sample test of scale. Equivalent to R's mood.test(). NaN values are dropped; ties get the average of the scores of their positions.

There is also a formula form, moodTest("y ~ g", data, options) (next overload).
Parameters
- x: Sample
- y: Sample
- Optionaloptions: MoodTestOptions
Returns HTest
Example
```
const r = moodTest([0.8, 1.9, 2.4, 3.1, 4.6, 5.0], [2.6, 2.9, 3.0, 3.3, 3.5]);
r.statistic; // 2.0919054414739633
r.pValue;    // 0.03644697523591335

Parameters
- formula: string
  "y ~ g".
- data: DataFrame
  The data frame: an object of columns (null or NaN for a missing value).
