For the regression model y=βo+ β1x1+…+β1x1, where y is q ×1 random vector and βiis q ×1 parameter vecter, the independent variable selection rule based on the CP statistics under the condition of β≥ 1: The selection of the independent yariable subset P can be done through the calculation of Cp corresponding to P, which satisfied CP≤γα(t,n-t-1,q).
③A multiple linear stepwise regression analysis was used with ISI as the dependent variable. The levels of Mg 2+ in erythrocytes ( X 1 ), 24 hour urinary excretion of Ca 2+ ( X 2 ) and Mg 2+ ( X 3 ) as independent variables, and X 1, X 2 were used in equations.
To the second order linear hyperbolic equation with two independent variables Auxx+2buxy+cuyy+ dux+eux+g=0 when its coefficients a,b,c are constants and d,e satisfy given conditions,we may utilize the transformation T:ζ=a11x+a12y, η=a21x+a22y to make it as first order linear ordinary differential equation for solving. At the same time,we give the discrimination theorem and application method.
(4)The multiple stepwise regression analysis in which HDL-C as a dependable variable and age, sex, BMI, WHR, FBG, SP, DP, TG, HOMA-IR as independent variables showed that sex, HOMA-IR, BMI, age, TG, FBG and WHR were influencing factors of HDL-C.

METHODS: Uricase reaction curve was monitored by absorbance at 293 nm, and it was fit to the integrated Michaelis Menten rate equation with the predictor variable of reaction time for irreversible, single substrate reaction with the background absorbance as a nonlinear parameter while K m as a preset constant.
The apparent kinetic parameters(apparent Michaelis-Menten constant,K_(mapp),and apparent maximal reaction rate,V_(mapp)) were estimated by nonlinear fitting reaction curve to the integrated Michaelis-Menten rate equation with the predictor variable of reaction time.
用反应时间为自变量的积分速度方程拟合反应曲线确定表观米氏常数(apparentM ichaelis-M enten constant,Km app)和表观最大反应速度(apparentm axim al reaction rate,Vm app).
In the present paper we obtain an approximate first-order differential equation for the frequency squared, using the filling level as the independent variable.
In order to avoid introducing an extra independent variable, we consider the case when there are droplets or particles with some finite set d2? dn of dimensions in the mixture.
Conditions under which an operator obtained as a perturbation of multiplication by the independent variable is spectral
Conditions are studied under which the perturbed operator of multiplication by the independent variable is spectral in the sense of Dunford and Bade.
Upper and lower bounds are obtained for the absolute value of a canonical product that take into account the dependence of the product on the argument of the independent variable, as well as the arguments of the zeros.
Hence, we developed QSAR models based on a large set of theoretical molecular descriptors using ridge regression methodology, which overcomes this limitation and also because the independent variables are highly intercorrelated.
A total of 700 experimental data points were correlated using Rayleigh versus Nusselt number in various forms, based on different independent variables.
For independent variables, different rated values of the physicochemical parameters of data for complexes are used.
The difficulties associated with its solution are the result not only of the large number of independent variables, seven in the general case, but also of the very complicated structure of the collision integral.
Moreover, if in linearization we take the coordinates in planar flow as independent variables, then the flow past concave and convex corners is described in exactly the same fashion.
Kronecker webs, bihamiltonian structures, and the method of argument translation
Taking a specific determination of its argument and studying its limit when approaching the Shilov boundary, we are able to define a ?-valued,G-invariant kernel for triples of mutually transversal points inS.
We also extend the principle above to complex functions: If a complex function has a spectral gap at the origin then the variation of argument of this function must be large.
This result combined with the matrix analog of the Hilbert transform leads to variety of new explicit inversion formulas for the Radon transform of functions of matrix argument.
The methods rely on the energy analysis and a scale argument.
