where D indicates employment (D = 1 if the respondent is employed and D = 0 otherwise), Z is a vector of explanatory variables, is a vector of unknown parameters, and Φ is the cumulative distribution function of the standard normal distribution. Estimation of the model yields results that can be used to predict this employment probability for ...

In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value evaluated with respect to the conditional probability distribution. If the random variable can take on only a finite number of values, the "conditions" are that the variable can only take on a subset of ...

Quantile regression is a type of regression analysis used in statistics and econometrics. Whereas the method of least squares estimates the conditional mean of the response variable across values of the predictor variables, quantile regression estimates the conditional median (or other quantiles) of the response variable.
An example application of the method of moments is to estimate polynomial probability density distributions. In this case, an approximating polynomial of order is defined on an interval [,]. The method of moments then yields a system of equations, whose solution involves the inversion of a Hankel matrix. [2]
In the simplest case, the "Hodges–Lehmann" statistic estimates the location parameter for a univariate population. [2] [3] Its computation can be described quickly.For a dataset with n measurements, the set of all possible two-element subsets of it (,) such that ≤ (i.e. specifically including self-pairs; many secondary sources incorrectly omit this detail), which set has n(n + 1)/2 elements.
For these two expressions to be well-defined, we require that all elements of H tend to 0 and that n −1 |H| −1/2 tends to 0 as n tends to infinity. Assuming these two conditions, we see that the expected value tends to the true density f i.e. the kernel density estimator is asymptotically unbiased ; and that the variance tends to zero.
