Multivariate regression is a powerful statistical technique that allows researchers to explore multiple predictors simultaneously, to adjust for confounding, to test for interactions, and to improve predictions.
Ordinary least squares (OLS) regression is an optimization technique applied to linear regression models to minimize the sum of squared differences between observed and predicted values. It obtains a straight line as close as possible to data points.
Multiple linear regression analysisBackground Previous studies indicated a strong association between hyperkalemia and lung squamous cell carcinomas (LSCC). However, the underlying mechanism is not fully understood so far. Methods Literature-based data mining was conducted to identify genes, molecule, and...

The last assumption of the linear regression analysis ishomoscedasticity. The scatter plot is good way to check whether the data are homoscedastic (meaning the residuals are equal across the regression line). The following scatter plots show examples of data that are not homoscedastic (i.e., hete...
These ideas are illustrated on common statistical models, including the multiple linear regression model, the hierarchical mean model, the logistic regression model, and the proportional hazards model.The book begins with an outline of the similarities and differences between Bayesian and the likelihood ...
we intended to identify the influence of these variables on CoC, not to predict the development of the CoC of LSPs (this also verifies the application of a stepwise multiple linear regression). Nonetheless, the results allow conclusions regarding which significantly influential variables should be con...
prediction can be replicated by a hierarchy of three simple multiple-linear regression (MLR) models that take as predictors:Vmonly (standard wind-only baseline);Vm,f, and the radius of 8 ms−1,r8(analogous to the prevailing empirical model6); andVmand\(\frac{1}{2}f{r_8}\)(new ...
This analysis used multinomial logistic regression, which simultaneously compares between exposure groups the odds of multiple, mutually-exclusive outcomes using a single chosen reference group. As per convention, we used BMI 18.5–24.99 kg/m2 as the reference group. All analyses adjusted for age and...
