Inverse Probability ” of 1930
In 1930 RA. Fisher put forward the fiducial argument. This paper discusses the argument and its origins in Fisher's earlier work. It also emphasises the contribution of Mordecai Ezekiel to the 1930 publication.
متن کاملInverse probability weighting.
Statistical analysis usually treats all observations as equally important. In some circumstances, however, it is appropriate to vary the weight given to different observations. Well known examples are in meta-analysis, where the inverse variance (precision) weight given to each contributing study varies, and in the analysis of clustered data. Differential weighting is also used when different p...
متن کاملRealizableMonotonicity and Inverse Probability Transform
A system (Pα : α ∈ A) of probability measures on a common state space S indexed by another index set A can be “realized” by a system (Xα : α ∈ A) of S-valued random variables on some probability space in such a way that each Xα is distributed as Pα. Assuming that A and S are both partially ordered, we may ask when the system (Pα : α ∈ A) can be realized by a system (Xα : α ∈ A) with the monoton...
متن کاملCombining Multiple Imputation and Inverse-Probability Weighting
Two approaches commonly used to deal with missing data are multiple imputation (MI) and inverse-probability weighting (IPW). IPW is also used to adjust for unequal sampling fractions. MI is generally more efficient than IPW but more complex. Whereas IPW requires only a model for the probability that an individual has complete data (a univariate outcome), MI needs a model for the joint distribut...
متن کاملSmall Ball Probability, Inverse Theorems, and Applications
Let ξ be a real random variable with mean zero and variance one and A = {a1, . . . , an} be a multi-set in R. The random sum SA := a1ξ1 + · · ·+ anξn where ξi are iid copies of ξ is of fundamental importance in probability and its applications. We discuss the small ball problem, the aim of which is to estimate the maximum probability that SA belongs to a ball with given small radius, following ...
