In addition, although is a nonlinear function of pH, it can be approximated over the physiologic range by a more computationally convenient linear form, such that for plasma the following explicit expression is obtained [ 11, 12, 15]: SID = [HCO3-] + CAlb (8.0pH - 41) + CPhos (0.30pH - 0.4) (4) Where CAlb and CPhos are plasma albumin and phosphate concentrations, respectively.
In practice, it is often more convenient to perform the linear fitting to an alternative set of Fourier functions.
Logistic regression approaches are more convenient than probit or linear probability models for analyzing health care use because the estimated coefficients can easily be converted into odds ratios [ 37- 39].We choose to use a multinomial logit selection model.
It is sometimes more convenient to work with the linear predictor from a logistic regression, that is, the log-odds of treatment or logit, since its distribution is likely to be closer to normal.
However, it would be more convenient for applications to adopt the linear regression analysis for determining the correlation between the GCR and PET for the percentage of areas that are comfortable (Cf).
Hence, the linear flow method is more convenient and is a significant alternative for simulating the behavior in MFHW (Wang et al. 2016a).
More specifically, we utilize the fact that 2D harmonic basis images at different poses are related by close-form linear transformations, and give a more convenient transformation matrix to be directly used for basis images.
It can be shown that the area under the ROC curve is a linear transformation of the AUAC, and more convenient since it ranges from 0 to 1.
Therefore, a linear model is practically more preferable and more convenient and efficient to solve.
However, in some cases, it is more convenient to fit current-potential data to simpler forms (i.e. linear) [34].
