What does a meta-regression show?
Meta-regression is an extension to subgroup analyses that allows the effect of continuous, as well as categorical, characteristics to be investigated, and in principle allows the effects of multiple factors to be investigated simultaneously (although this is rarely possible due to inadequate numbers of studies) ( …
What do my regression results mean?
The sign of a regression coefficient tells you whether there is a positive or negative correlation between each independent variable and the dependent variable. A positive coefficient indicates that as the value of the independent variable increases, the mean of the dependent variable also tends to increase.
How to interpret results of meta-analysis ( PDF )?
Since there are no imputed data points (based on the Trim-and-Fill method), the funnel plot indicates there is no asymmetry in the distribution of effect sizes. However, if we would find asymmetry, the Trim-and-Fill method would impute one or more studies and therewith adjust the combined effect size for the potentially missing studies.
Which is the output of a regression analysis?
When you use software (like R, Stata, SPSS, etc.) to perform a regression analysis, you will receive a regression table as output that summarize the results of the regression. Arguably the most important numbers in the output of the regression table are the regression coefficients.
How to interpret regression coefficients-statology [ step by step guide ]?
Suppose we run a regression analysis and get the following output: Term Coefficient Standard Error t Stat P-value Intercept 48.56 14.32 3.39 0.002 Hours studied 2.03 0.67 3.03 0.009 Tutor 8.34 5.68 1.47 0.138
How to interpret the intercept of a regression coefficient?
Let’s take a look at how to interpret each regression coefficient. The intercept term in a regression table tells us the average expected value for the response variable when all of the predictor variables are equal to zero. In this example, the regression coefficient for the intercept is equal to 48.56.
