+/**
+ * Default delta degrees of freedom for the standard deviation (std).
+ *
+ * The default is set to `1`,
+ * meaning DataFrame uses [Bessel’s correction](https://en.wikipedia.org/wiki/Bessel%27s_correction) to calculate the
+ * "unbiased sample standard deviation" by default.
+ * This is also the standard in languages like R.
+ *
+ * This is different from the "population standard deviation" (where `ddof = 0`),
+ * which is used in libraries like Numpy.
