Inverse Probability of Treatment Weighting (Propensity Score) using the Military Health System Data Repository and National Death Index
Published on: January 8, 2020
Abstract:
Shortly after preparing the re-based 1991 population estimates, the Office for National Statistics produced provisional population estimates by legal marital status (for England and Wales as a whole). These provisional estimates were calculated using a marital status distribution for 1991 that was updated from the 1981 Census. These estimates have now been revised to incorporate marital status information from the 1991 Census. This article outlines the options for re-basing the estimates, the method used, and assesses the effect of the revision on the rates of marriage, divorce and mortality by single year of age. The main differences between the provisional and final re-based estimates in 1991 are: estimates of widowed men and women are 7 per cent and 2 per cent higher, respectively, estimates of divorced men and women are 2 per cent and 3 per cent lower, re-marriage rates (amongst the divorced or widowed) for men 50-59 increased, and mortality rates for single and divorced men increased for those aged over 70.

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
Equivalent Couples
Two couples are considered to be equivalent if they produce the same rotational effect on a rigid body. In other words, the two couples have the same magnitude and act in the same direction, causing the same angular displacement or acceleration in the body.
For instance, consider two couples lying in the plane of the page, with one having a pair of equal...
