Table 7.
Estimated step break 1995 for monthly and quarterly sample frequencies.
| Burglary | Larceny | MVT | Robbery | AA | Murder | Rape | |
|---|---|---|---|---|---|---|---|
| Step break 95:01 | |||||||
| Monthly freq | −3.98* | −8.00 | 1.67 | 0.52 | 0.20 | −0.09* | −0.12 |
| Quarterly freq | −3.77* | −4.58 | 3.00* | 0.65 | 0.16 | −0.10* | −0.10 |
| Abs.diff | 0.21 | 3.42* | 1.33 | 0.13 | 0.04 | 0.01 | 0.02 |
In our analysis we consider the BSM with a deterministic slope for the trend component and with intervention effects; the sample sizes are 324 (monthly) and 108 (quarterly); MVT = motor vehicle theft; AA = aggravated assault; abs.diff = absolute difference between monthly and quarterly estimates; the asterisk* indicates statistical significance.
