总体最小二乘法(Total Least Squares)拟合直线 最小二乘法是最小化每个点到直线的垂直误差,由于误差采用的是垂直误差,导致越接近垂直线(平行于y轴),拟合效果越差,无法拟合垂直线。 通过最小化每个点到直线的距离误差可以解决最小二乘法无法拟合垂直线的问题,也就是总体最小二乘法(Total Least Squares)。 总体...

In statistics, ordinary least squares (OLS) or linear least squares is a method for estimating the unknown parameters in a linear regression model. This method minimizes the sum of squared vertical distances between the observed responses in the dataset, and the responses predicted by the linear ...
{MAX}\,\)represents the maximum number of edges a genetic regulatory network would have given its number of nodes. This equation represents a relationship between the number of interactions and the number of nodes given a specific graph density. Using ordinary least squares regression (OLS), it...

Experimentally, we show that for uncontaminated, realizable data, the LeastSquares algorithm performs best, but in the presence of contamination or DAG misspecification, CauchyEst, CauchyEstTree and BatchAvgLeastSquares respectively perform better. Example Prerequisites Python 3.6+ networkx argpase itertoo...
‘slave’ devices. Instead, spectral data from two spectrometers are fused to create a master spectrum, while independent spectral data serve as slave spectra. We developed an ensemble stacking model, incorporating partial least squares regression (PLSR), support vector regression (SVR), and ridge ...
The two-stage least squares method (2SLS) is used for the estimation. The results of columns (1) and (2) in Table 8 indicate that a new energy company can boost its total factor productivity by embracing digital transformation. The Kleibergen–Paap rk LM statistic and the Kleibergen–Paap ...
This algorithm is available in an open access software TIGRE toolbox: a MATLAB/Python GPU toolbox for X-ray CT image reconstruction [20]. The AwPCSD algorithm was developed to reconstruct the volumetric image from cone-beam CT projection data. The algorithm required two phases implemented ...
