..., which was a combination of linear extrapolation and qualitative judgments. Unfortunately, linear extrapolation excludes known risk factors and is inconsistent with long-standing demographic patterns, such as the smoothness of age profiles. Modern statistical methods typically outperform even the best...

...Maarten J. Bijlsma; Rhian M. Daniel; Fanny Janssen; Bianca L. De Stavola Abstract Many methods have been proposed to solve the age-period-cohort (APC) linear identification problem, but most are not theoretically informed and may lead to biased estimators of APC effects. One exception...

... factors that determine the discrete outcome under examination. In linear models, the standard solution to this potential endogeneity bias is an estimator such as two-stage least squares. These methods have been extended to models with limited dependent variables, but there is little information...

To see how results vary, we analyze 1912 estimates (means; proportions; linear regression; and simple and multinomial logistic...

Our approach is to add time-series stochasticity to linearized versions of each process. We derive both Monte Carlo and analytic methods for estimating forecast...

These methods permit the development of more elaborate models of changing fecundability and of heterogeneity in postpartum amenorrhea. 16 1...

The precision of the usual projection e T (= EX T ) is studied by a family of prediction intervals of linear functions of the vector of deviations X T — e T , which has a preassigned probability level. This family is obtained by a multi-normal approximation...

These estimates are obtained by using a technique which improves on Brass's method in that it suppresses the as- sumption of constant mortality and introduces instead assumptions about linear and nonlinear changes in mortality risks affecting...

An additional advantage of our census-based estimation method is the extension backward of the birth and infant mortality series for years prior to published estimates of registered births, enabling previously impossible...
