Modern Regression


In statistics, regression analysis includes any techniques for modelling and analyzing several variables, when the focus is on the relationship between a dependent variable and one or more independent variables. More specifically, regression analysis helps us understand how the typical value of the dependent variable changes when any one of the independent variables is varied, while the other independent variables are held fixed.

Evolutionary Modeling-based Approach for Model Errors Correction :...

By: W. Jiang; L. Wang; W. Zhang; W. P. He; S. Q. Wan

Description: Yangzhou Meteorological Office, Yangzhou, China. The inverse problem of using the information of historical data to estimate model errors is one of the science frontier research topics. In this study, we investigate such a problem using the classic Lorenz (1963) equation as a prediction model and the Lorenz equation with a periodic evolutionary function as an accurate representation of reality to generate observational data.

Description: Institute of Applied Physics RAS, Nizhniy Novgorod, Nizhniy Novgorod, Russia. Drag and mass exchange coefficients are calculated within a self-consistent problem for the wave-induced air perturbations and mean velocity and density fields using a quasi-linear model based on the Reynolds equations with down-gradient turbulence closure. This second part of the report is devoted to specification of the model elements: turbulent transfer coefficients and wav...

By: I. Fer; M. Bakhoday Paskyabi

Description: Geophysical Institute, University of Bergen, Allégaten 70, 5007 Bergen, Norway. Observations were made in the near-surface layer, at about 8 m depth in 132 m deep water off the coast of Ålesund in Norway, for a duration of 2.5 months in late 2011. The measurement period covers the passage of two low pressure systems with substantial wind and wave forcing. The time series of the dissipation rate of turbulent kinetic energy, ε, and the estimates of surfac...

The Sunspot Cycle Length – Modulated by Planets? : Volume 1, Issue...

By: J.-e. Solheim

Description: formerly at: Department of Physics and Technology, Universtity of Tromsø, Norway. The Schwabe frequency band of the sunspot record since 1700 has an average period of 11.06 yr and contains four major cycles, with periods of 9.97, 10.66, 11.01 and 11.83 yr. Analysis of the O–C residuals of the timing of solar cycle minima reveals that the solar cycle length is modulated by a secular period of about 190 yr and the Gleissberg period of about 86 yr.

By: Walt Whitman; Neil Azevedo, Editor

Walt Whitman (1819-1892) is widely considered to be the greatest and most influential of all American poets. LEAVES OF GRASS, Whitman's sole book published at his own expense, represents almost the entirety of his poetical output. The first edition of LEAVES OF GRASS, which he would continue to revise over the course of his life expanding and rewriting it until the year of his death, appeared in 1855. This volume represents the final edition, commonly referred to as the ...

O Captain! My Captain! O Captain! my Captain! our fearful trip is done, The ship has weather’d every rack, the prize we sought is won, The port is near, the bells I hear, the people all exulting, While follow eyes the steady keel, the vessel grim and daring;                     But O heart! heart! heart!                          O the bleeding drops of red,                               Where on the deck my Captain lies,                                    Falle...

By: Umesh Gaur

Technical Reference Publication

Introduction: Heat capacity is the key macroscopic material property which is well enough understood to permit, when determined over a wide range of temperature, the establishment of connection to the microscopic structure and motion. Through its knowledge the other thermodynamic functions (enthdpy, entropy, and Gibbs energy) can be derived. This is the first paper in a series of critical discussions of the heat capacity of linear macromolecules.

Technical Reference Publication

Introduction: Recently the present authors published compilations of cross-section data for the collision of electrons and photons with nitrogen (N,) and oxygen (0,)2 molecules. These molecules are the major constituents of the Earth's atmosphere. Atomic oxygen (0) is also important in the upper atmosphere of the Earth, since it is the most abundant species at heights between 200 and 600 km. Furthermore, atomic oxygen plays a significant role in the atmospheres of other ...

Mathematics document containing theorems and formulas.

Excerpt: Before you start Statistics starts with a problem, continues with the collection of data, proceeds with the data analysis and finishes with conclusions. It is a common mistake of inexperienced Statisticians to plunge into a complex analysis without paying attention to what the objectives are or even whether the data are appropriate for the proposed analysis. Look before you leap! Formulation The formulation of a problem is often more essential than its solution ...

Tidal Current Analysis Procedures and Associated Computer Programs

Introduction: The National Ocean Service (NOS) has been charged with producing tidal current tables for the coastal areas of the United States. Tidal currents are almost always the strongest current experienced by vessels operating offshore and for considerable distances inside of bays and river estuaries. Tidal currents are usually fastest where water level fluctuations on wide continental shelves are amplified as they approach the coast and water is forced through a na...
