Published: 01 August 1993
...Frans van Poppel; Joop de Beer Abstract This article discusses different procedures for measuring the effects of judicial changes on divorce rates. It presents an alternative model and applies it to a historical time series for the Netherlands. In this model, intervention variables were added...

... the problem formally. These analyses were organized within two design structures: a control-group interrupted time-series design and a difference-in-differences design. In these analyses, Oklahoma County showed an interpretable, consistent, and significant increase in births. Second, we used graphical...

... in the expected fashion with suicide rates. Such ecological studies of suicide adopt both cross-sectional and time-series research designs and thus exploit different components of overall variation in suicide rates. The connection between economic conditions, often measured with unemployment rates...

... changes differ over geographic and social space. Space-time analysis has always been important in studying fertility transitions, for example. However, demographers have seldom used formal statisti- cal methods to describe and analyze time series of maps. One formal method, used widely in epidemi- ology...

... difference helps to explain our finding that regression analysis of 17 country-series shows that life expectancy losses correlate with income inequality across countries but not across time. Decomposition analysis also provides information for a discussion of the reasons for particularly high lifetime losses...

... (NCHS) for the U.S. Registration Area. The LEs have been published many different times; for an accessible copy, see Arias (2004:34, table 12). We measured variation for these LEs as the absolute values of the differences between two successive years (e.g., 1971 minus 1970). The differences for 1917...

...Mark E. Hill Abstract As an alternative to survival analysis with longitudinal data, I introduce a method that can be applied when one observes the same cohort in two cross-sectional samples collected at different points in time. The method allows for the estimation of log-probability survivorship...

..., yielding a higher probability of divorce by interview for earlier cohorts relative to more recent cohorts even if divorce risks are identical across all marriage cohorts. We confirm this possibility by using a series of discrete-time hazard logistic regressions to investigate the sensitivity of estimates...

..., with associated measures of uncertainty, of fertility, mortality, immigration, and emigration within a cohort projection model. The methodology may be adapted to handle different data types and sources of information. To illustrate, we analyze time series data for the United Kingdom and forecast the components...

... and different time periods. From 1985 to 1996, the fraction of women aged 15–44 who were eligible for Medicaid coverage for a pregnancy increased more than 20 percentage points. When we use a state and year fixed-effects model with a limited set of covariates, our estimates indicate that fertility increases...

Therefore, in order to corroborate the observations based upon the ratios and to specify differentials in more concrete terms, a series of "time-lag" statistics have been calculated...
