摘要：This paper discusses the falsifiable implications of the heterogeneous mixing model of infectious disease. It is shown that the model implies a proportional hazard restriction across the set of susceptible survival functions of the subpopulations. Using this implication, the testable restrictions and identification of the model are discussed when subpopulations are observable as well as unobservable.

摘要：The covariance matrix of a first order moving average process is expressed as the product of the covariance matrix of the dual autoregressive process of order one and a near identity matrix. Its inverse is then obtained. The closed form of the likelihood function is derived. A comparison is made with some approximate likelihood functions.

摘要：The bandwidth of a spectral estimator is a measure of the minimum separation in frequency between approximately uncorrelated spectral estimates. We determine an effective bandwidth measure for multitaper spectral estimators, a relatively new and very powerful class of spectral estimators proving to be very valuable whenever the spectrum of interest is detailed and/or varies rapidly with a large dynamic range. The multitaper spectral estimator is the average of several direct spectral estimator...

摘要：We define a simple kernel procedure based on marginal integration that estimates the relevant univariate quantity in both additive and multiplicative nonparametric regression.
