+ * General approach for the tests below:
+ * We only used timestamps in milliseconds, 0 ms, 1 ms, and 2 ms, to be sure that
+ * we are well within the HORIZON range.
+ * When specifying the expected values of the coefficients, we treat the x values as if
+ * they were in ms. Then, to adjust for the time units, the coefficients get progressively
+ * multiplied by powers of 1E3.
+ * For example:
+ * data: t(ms), x
+ *        1 ms, 1
+ *        2 ms, 4
+ *        3 ms, 9
+ * The coefficients are (0, 0, 1).
+ * In the test, we would convert these coefficients to (0*(1E3)^0, 0*(1E3)^1, 1*(1E3)^2).
