可以使用不同的描述方法,发现此sample是一个偏斜分布: . 置信区间的本质: The length of the confidenceinterval indicates the precision of the estimate, or how well we have “pinned down” μ.Long confidence intervals indicate poor precision; short confidence intervals indicategood precision. 如图:比较两...
We conducted a stepwise hierarchical regression analysis with anticipated identity changes in retirement as the outcome variable. Continuous variables were mean-centered. In the first step, we entered the main hypothesized predictor: organizational commitment. For the second step we entered group membership...
Regression models were developed that permit us to examine and comprehend the relationship between two or more essential variables. Regression analysis is carried out using a process that makes it easier to determine which aspects are crucial, which may b...
Spearman correlation analysis and multiple stepwise regression analysis were conducted to identify independent factors. The ROC curve was generated to analyze the value of serum 1,5-AG in screening diabetes. The optimal cut-off point was confirmed based on the Youden index. A two-tailed P value...
Therefore, in order to converge quickly on a near-optimal model, a backward stepwise regression [40] selection procedure was adopted. For the linear ARX model, the model selection algorithm begins by including all of the considered input variables in the calculation of the AIC. The algorithm ...
A linear hierarchical (stepwise) regression analysis (ordinary least square) was used to test H1. For H2, we conducted a moderation analysis using Hayes PROCESS macro (version 3.4) for SPSS (Hayes 2012, 2018). PROCESS uses an ordinary least squares or logistic regression-based path analytical ...
The presence of an outlier would greatly increase the value of Sy.x. Therefore, we use an alternative method to quantify the scatter of points around the curve generated by robust nonlinear regression. We quantify the scatter by calculating the 68.27 percentile of the absolute values of the resi...
Here, we use glioblastoma as a blueprint for a challenging solid tumor to cross-compare mouse and human CAR T cells, CAR NK cells, and CAR macrophages. Glioblastoma, the most common and aggressive primary brain tumor in adults, lacks a curative treatment and remains one of the most difficult...
