Evolving polynomial regression has also been proposed as a method for better model identification. The proposed procedure was tested on experimental data of Pb(II) and Cd(II)-propanoate, measured using differen
Significance tests on coefficients of lower-order terms in polynomial regression models are affected by linear transformations. For this reason, a polynomial regression model that excludes hierarchically inferior predictors (i.e., lower-order terms) is considered to be not well formulated. Existing vari...
In thepolynomial regression model, we assume that the relationship between the dependent variable and a single independent variable is described by a polynomial of some arbitrary degree. If you've already encountered the model ofsimple linear regression, where the relationship between the dependent and...
Suppose the specific value on the x-axis is 4 and we are doing linear regression. If you subtract 4 from the x values in your sample (without changing the y values), that seems to move your specific x value to 0. You can now perform linear regression through the origin, as described ...
In this paper, we propose a model adaptation algorithm based on maximum likelihood subband polynomial regression (MLSPR) for robust speech recognition. In this algorithm, the cepstral mean vectors of prior trained hidden Markov models (HMMs) are converted to the log-spectral domain by the inverse...

11 and 12, the parameters of the BASE, GB99 and the seven versions of M3 were refitted by weighted non- linear least squares using the model procedure in SAS/ ETS® software Version 9.3 (SAS Institute Inc. 2002 - 2004). In this regression analysis, residual correlations due to ...

The values of the EChP descriptors were generated for all molecules in the dataset and were used as input data for searching linear regression models able to explain the investigated properties (area and volume). Three different approaches were used, searching for additive, multiplicative, or full...
