Function propTrendTest

propTrendTest(x: Sample, n: Sample, score?: Sample): PropTrendTestResult
Chi-squared test for trend in proportions. Equivalent to R's prop.trend.test(x, n, score). The scores are the third argument or the option score (giving both is a RangeError).
Parameters
- x: Sample
  Numbers of events.
- n: Sample
  Numbers of trials.
- Optionalscore: Sample
  Scores of the groups. Default 1, 2, ..., k. A group with a NaN score is left out of the regression (as R's lm omits it), but its counts stay in the pooled proportion and the weights, as in R. Other scores must be finite, with at least two distinct values. With no events or only events (all proportions 0, or all 1) the test is not defined (an error, as in R).
Returns PropTrendTestResult
Example
```
propTrendTest([15, 10, 8, 4], [30, 30, 30, 30]).statistic; // 9.573428850537288
```

propTrendTest(
    x: Sample,
    n: Sample,
    options: PropTrendTestOptions,
): PropTrendTestResult
Chi-squared test for trend in proportions, with the scores in the options: propTrendTest(x, n, { score: [0, 1, 2, 4] }).
Parameters
- x: Sample
- n: Sample
- options: PropTrendTestOptions
Returns PropTrendTestResult
Example
```
propTrendTest([15, 10, 8, 4], [30, 30, 30, 30], { score: [1, 2, 3, 4] }).statistic; // 9.573428850537288
