As an important tool of atmospheric remote sensing, microwave radiometers are used for temperature profiling, and vapor and liquid column measurements (Hogg et al. 1983; Solheim et al.1998). Radiometer measurements are inexpensive compared to the cost of radar, and it can provide all-time observation in both cloudy and clear air situations. However, using radiometer measurements can be more dif...

We present an algorithm for computing the cumulative distribution function of the Kolmogorov{ Smirnov test statistic D n in the all-parameters-known case. Birnbaum (1952) gives an n-fold integral for the CDF of the test statistic which yields a function deened in a piecewise fashion, where each piece is a polynomial of degree n. Unfortunately, it is diicult to determine the appropriate limits o...

A smooth kernel estimator is proposed for multivariate cumulative distribution functions (cdf), extending the work of Yamato [H. Yamato, Uniform convergence of an estimator of a distribution function, Bull. Math. Statist. 15 (1973), pp. 69–78.] on univariate distribution function estimation. Under assumptions of strict stationarity and geometrically strong mixing, we establish that the proposed...

We propose parametric regression analysis of cumulative incidence function with competing risks data. A simple form of Gompertz distribution is used for the improper baseline subdistribution of the event of interest. Maximum likelihood inferences on regression parameters and associated cumulative incidence function are developed for parametric models, including a flexible generalized odds rate ...

Estimation accuracy of Horn and Schunck's classical optical ow algorithm depends on many factors including the brightness pattern of the measured images. Since some applications can select brightness functions with which to \paint" the object, it is desirable to know what patterns will lead to the best motion estimates. In this paper we present a method for determining this pattern a priori usi...

The local space density of galaxies as a function of their basic structural parameters –like luminosity, surface brightness and scalesize– is still poorly known. Our poor knowledge is mainly the result of strong selection biases against low surface brightness and small scalesize galaxies in any optically selected sample. We show that in order to correct for selection biases one has to obtain ac...

Low surface brightness galaxies, those galaxies with a central surface brightness at least one magnitude fainter than the night sky, are often not included in discussions of extragalactic gas at z < 0.1. In this paper we review many of the properties of low surface brightness galaxies, including recent studies which indicate low surface brightness systems may contribute far more to the local HI...

Gamma-ray bursts (GRBs) continue to confound astrophysicists nearly a quarter century after their discovery (1). Before the launch of CGRO, most scientists thought that GRBs came from magnetic neutron stars residing in a thick disk (having a scale height of up to ∼ 2 kpc) in the Milky Way (2,3). The data gathered by BATSE showed the existence of a rollover in the cumulative brightness distribut...

Fluorescence fluctuation spectroscopy provides information about protein interactions in the intercellular environment from naturally occurring equilibrium fluctuations. We determine the molecular brightness of fluorescent proteins from the fluctuations by analyzing the photon counting histogram (PCH) or its moments and demonstrate the use of molecular brightness in probing the oligomerization ...
