java - 如何将 double 组转换为集合？

Question

我有两个数组

   double arr[]=data.attributeToDoubleArray(4);
   double arr0[]=data.attributeToDoubleArray(0);

要计算常见 apache 中的 p 值，其记录如下:

 public double anovaPValue(Collection<double[]> categoryData)
               throws NullArgumentException,
                      DimensionMismatchException,
                      ConvergenceException,
                      MaxCountExceededException

       Computes the ANOVA P-value for a collection of double[] arrays.
       Preconditions:

        The categoryData Collection must contain double[] arrays.
        There must be at least two double[] arrays in the categoryData collection and each of these arrays must contain at least two values.

如何转换集合中的两个数组以便我可以使用上述函数？

你可以试试这个:

double arr[]=data.attributeToDoubleArray(4);
double arr0[]=data.attributeToDoubleArray(0);

List<double[]> newArr = Arrays.asList(arr, arr0);
