KERNEL REGRESSION ESTIMATION FOR INCOMPLETE DATA
... Statisticians working in any field are often interested in the relationship between a response variable Y and a vector of covariates Z = (Z1 , · · · , Zd ). This relationship can best be described by the regression function m(z) = E[Y |Z = z]. The regression function is estimated utilizing data whic ...

Sampling theory
... It is important to note that the sampling fraction is often very small in practice, i.e. f ≈ 0 . In fact, this is then equivalent to random sampling with replacement. It is also intuitively clear that replacement or non replacement no longer has an effect on the value of the estimator when the popul ...

... In the interval endpoint, b2 – tcse(b2) and b2 + tcse(b2), both b2 and se(b2) are random variables, since their value are not known until a sample of data is drawn. • The probability endpoints of the interval define an interval estimator of β2. The probability statement in Equation (5.1.13) says th ...

... of RIF (Y ; µ) on X is the same as the standard regression of Y on X. This explains why, in our framework, OLS estimates are valid estimates of the effect of X on the unconditional mean of Y . More importantly, we show that this property extends to any other distributional statistic. For the τ -quan ...

Derivative Estimation Based on Difference Sequence via Locally
... There are three main approaches of nonparametric derivative estimation in the literature: smoothing spline, local polynomial regression (LPR), and difference-based method. As for smoothing spline, the usual way of estimating derivatives is to take derivatives of spline estimate. Stone (1985) showed ...

German tank problem
In the statistical theory of estimation, the problem of estimating the maximum of a discrete uniform distribution from sampling without replacement is known in English as the German tank problem, due to its application in World War II to the estimation of the number of German tanks.The analyses illustrate the difference between frequentist inference and Bayesian inference.Estimating the population maximum based on a single sample yields divergent results, while the estimation based on multiple samples is an instructive practical estimation question whose answer is simple but not obvious.
