Measurement of the power spectral density of (stochastic) Brownian fluctuations of micro- and nano-devices is used frequently to gain insight into their mechanistic properties. Noise is always present in these measurements and can directly influence any parameter estimation obtained through a least-squares analysis. Importantly, measurements of the spectral density of stationary random signals,...

oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. for instance sea surface temperature (sst) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. the purpose of this thesis is to derive a relatively complete frame...

BACKGROUND The need to have a quantitative estimate of the uncertainty of prediction for QSAR models is steadily increasing, in part because such predictions are being widely distributed as tabulated values disconnected from the models used to generate them. Classical statistical theory assumes that the error in the population being modeled is independent and identically distributed (IID), but ...

A domain decomposition method for solving large bivariate scattered data fitting problems with bivariate minimal energy, discrete least-squares, and penalized least-squares splines is described. The method is based on splitting the domain into smaller domains, solving the associated smaller fitting problems, and combining the coefficients to get a global fit. Explicit error bounds are establish...

We adopted a person–organization (P–O) fit framework to examine applicant attraction to an organization in the context of Web-based recruitment. A total of 121 undergraduate business students participated in a two-stage study first by completing a paper-and-pencil survey and second, by visiting a fictitious recruitment Web site in which the researchers manipulated the fit feedback information p...

1 Anscombe’s term for such knowledge in Intention is “practical knowledge”. However, I have avoided that term as I wish to defend the idea that agents have a distinctive non-observational knowledge of their actions without being committed to her claims about the existence of a kind of knowledge with a reverse direction of fit from ordinary knowledge. 2 The idea originates in English speaking ph...

to assess seismic hazard, it is essential to estimate the potential seismicity, particularly estimation of size of the largest earthquake that can be identified by a distinct fault or earthquake source. one of the methods applied to estimate magnitude of earthquake is use of empirical relationships between magnitude and fault parameters. fault parameters for the earthquakes from early instrumen...

Lastly, I wish to illustrate and to stress the necessity of assessing goodness of fit by making use of several tests and not relying on only one or two such tests. Referring to Table 1, the xz test and the Runs test indicate that model 3 is a good fit, whereas the curved Rankits plot, the slow convergence, the non-linearity at the minimum sum of squares and the wide range of the coefficients of...

Description Extended Structural Equation Modelling (SEM). Models may be specified with reticular action model (RAM) matrices or paths,linear structural relations (LISREL) matrices or paths, or directly in matrix algebra. To increase modularity, model expectations,fit functions, and optimizers can be easily interchanged. Fit functions include full information maximum likelihood (FIML),maximum li...
