Backward and forward selectionThere are various methods to add or remove variables to determine the best possible model.In the backward method, iterations start with considering all the variables and we will remove variables one by one until all the prescribed statistics are met (such as no ...
应用统计学-回归分析 拟合度使用r^2和Se来检验。 显著性检验中,对于线性model使用ANOVA,对于单独的回归系数使用t检验。 最小二乘法、贝叶斯和最大似然都可用于求回归参数,最小二乘法是最小化

Consequently, by employing such a triplet loss and applying a local error-backpropagation algorithm, the SI increases layer by layer. Thus, a forward-backward learning algorithm for a CNN is established, where all layers are trained sequentially, as depicted in Fig. 1. In the following, ...
This study explored whether instructing participants to make forward or backward joystick movements in response to morality words is consistent with the conceptual metaphor MORAL IS MOVING FORWARD/IMMORAL IS MOVING BACKWARD in Chinese-English bilinguals’ first and second languages. Chinese-English bilingual...
In backward mapping, the evaluation of the volume rendering integral (Equation 11.1) is a Riemann sum along viewing rays. In forward mapping, we assume that the reconstruction kernels do not overlap and can be integrated separately using Equation 11.7. The volume rendering integral Equation 11.1 ...
Among many developed methods, forward and stepwise feature selection regression remained widely used due to their simplicity and efficiency. However, they all involving rescanning all the un-selected features again and again. Moreover, many times, the backward steps in stepwise deem unnecessary, as ...
These data allow us for the first time to identify “forward” citations received by applications before grant, as well as “backward” citations in those applications, and classify both types as blocking (submitted mainly by examiners), or examiner or applicant non-blocking citations. ...
