| /* |
| * Special care must be taken when constructing tests for LeastSquaresVelocityTrackerStrategy |
| * getEstimator function. In particular: |
| * - inside the function, time gets converted from nanoseconds to seconds |
| * before being used in the fit. |
| * - any values that are older than 100 ms are being discarded. |
| * - the newest time gets subtracted from all of the other times before being used in the fit. |
| * So these tests have to be designed with those limitations in mind. |
| * |
| * 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 |
