"It is disingenuous to use strictly population proportions without accounting for reported crime," said Paul J. Browne, the Police Department's chief spokesman.
Teenagers are more in need of seat belts than other drivers, the experts said, because they are about twice as likely as older drivers to be in a crash, taking into account miles driven and population proportions.
For qualitative variables, point and interval estimates of the difference between population proportions can be constructed by considering the difference between sample proportions.
When fitnesses are equal, population proportions remain at stable equilibrium.
Assuming different population proportions, the marginal effect continues to be around 0.33 %.
Since the true population proportions are unknown, the WESML will be run as a robustness check under two different hypothesized true population proportions of miscarriages (15 and 20%%) to verify whether results would change.
When confidence intervals of two population proportions are compared and did not overlap, their differences are considered to be statistically significant (Schenker and Gentleman 2001).
The modest changes in population proportions between 2002 06 and 2006 10 are matched by the modest changes in the transfer rates.
Dynamic models typically employ the kinds of calculations involved in static models to depict actual change over time in population proportions.
On the whole population proportions of patients classified as "over-paralyzed," "well-paralyzed," or "under-paralyzed" differed significantly when results for clinical assessments were compared with results obtained with facial and ulnar TOF measurements (Fig. 2).
The BD2 sample had an EO component with mean AAO of 20.9 years (±4.1) and a LO component with mean AAO of 38.2 years (±11.8) with population proportions of 44% and 56%, respectively.
