Statistics of the slope-method estimator.
The slope method has customarily been used and is still used for inversion of atmospheric optical parameters, extinction, and backscatter in homogeneous atmospheres from lidar returns. Our aim is to study the underlying statistics of the old slope method and ultimately to compare its inversion performance with that of the present-day nonlinear least-squares solution (the so-called exponential-c...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Statistics of the Spectral Kurtosis Estimator
Spectral Kurtosis (SK; defined by Nita et al. 2007) is a statistical approach for detecting and removing radio frequency interference (RFI) in radio astronomy data. In this paper, the statistical properties of the SK estimator are investigated and all moments of its probability density function are analytically determined. These moments provide a means to determine the tail probabilities of the...
متن کاملStatistics of the log-det estimator.
The log-det estimator is a measure of divergence (evolutionary distance) between sequences of biological characters, DNA or amino acids, for example, and has been shown to be robust to biases in composition that can cause problems for other estimators. We provide a statistical framework to construct high-accuracy confidence intervals for log-det estimates and compare the efficiency of the estim...
متن کاملA Preliminary Test Estimator in Circular Statistics
Submit Manuscript | http://medcraveonline.com on PTEs and Stein-type estimators for various linear models. In statistical inference, the use of prior information on other parameters in a statistical model, usually leads to improved inference on the parameter of interest. Prior information may he (i) known and deterministic which is then incorporated into the model in the form of constraints on ...
