چکیده
Summary Regression analysis methods, such as linear regression for continuous outcomes and logistic binary outcomes, have been widely used in medical research data many years. However, there instances of misconceptions misinterpretations results within the community. Univariate multiple analyses are commonly by publications to identify factors that significantly correlated with outcome. In this manuscript, we critically evaluate validity approach. Our findings indicate method is invalid should be completely disregarded researchers.

Multivariate Analysis Versus Multiple Univariate Analyses
The argument for preceding multiple analysis of variance (ANOVAS) with a multivariate analysis of variance (MANOVA) to control for Type I error is challenged. Several situations are discussed in which multiple ANOVAS might be conducted without the necessity of a preliminary MANOVA. Three reasons for considering a multivariate analysis are discussed: to identify outcome variable system construct...
متن کاملInference for correlated effect sizes using multiple univariate meta-analyses
Multivariate meta-analysis, which involves jointly analyzing multiple and correlated outcomes from separate studies, has received a great deal of attention. One reason to prefer the multivariate approach is its ability to account for the dependence between multiple estimates from the same study. However, nearly all the existing methods for analyzing multivariate meta-analytic data require the k...

متن کاملSome Modifications to Calculate Regression Coefficients in Multiple Linear Regression
In a multiple linear regression model, there are instances where one has to update the regression parameters. In such models as new data become available, by adding one row to the design matrix, the least-squares estimates for the parameters must be updated to reflect the impact of the new data. We will modify two existing methods of calculating regression coefficients in multiple linear regres...
