This column explores the principles and practice of such plot-making, considering both wide and long (panel or longitudinal) data structures in which such data may appear. Applications include analysis of change over time or space and indeed any kind of correlation or comparison between variables....
The publication bias was evaluated by Begg's funnel plot and Egger's line regression test. All the data analysis was done by STATA12.0 software (Stata Corporation, College Station, TX, USA). Eleven case-control studies were included in our present meta-analysis. We found significant statistical...
4 screeplot — Scree plot of eigenvalues Remarks and examples stata.com Cattell (1966) introduced scree plots, which are visual tools used to help determine the number of important components or factors in multivariate settings, such as principal component analysis and factor analysis; see [MV] ...
A recent paper in the Lancet showed that eating cereal in the first trimester increased the probability of a male baby to 0.55. They had done 262 tests on various diets and found the most significant one. A plot of the p-values (done by a critic of the paper) showed a perfect ...
The data havenooutliers:Outliers are observations that don’t follow the same patterns as the rest of the data. A scatterplot is one way to check for outliers—look for points that are far away from the others. The relationship is linear:“Linear” means that the relationship between the ...
To test to see whether your two variables form a linear relationship you simply need to plot them on a graph (a scatterplot, for example) and visually inspect the graph's shape. In the diagram below, you will find a few different examples of a linear relationship and some non-linear ...
(a) Box plot: proportions of patients with a deletion involving the whole RB1 gene (both breakpoints out of RB1) or part of RB1 (one breakpoint in RB1). (b) One-factor analysis. We found no correlation between the parental origin of the deletion and deletion size, Rb phenotype (...
Publication bias was examined via funnel plot and Egger's test. Sensitivity analyses were predefined. Meta-analyses adhered to GRADE approach for inflammatory biomarkers/outcomes evaluation. Results: Patients with peri-implantitis exhibited elevated levels of serum C-reactive protein (CRP) (standard mean...
Publication bias of the included studies. Begg's funnel plot showed no substantial asymmetry (Fig. 10). Egger's regression test of publication bias of the seminal plasma zinc in infertile and normal males indicated little evidence of publication bias (t = − 0.19 P = ...
