DataParty uses Python 3.8.10 for data analysis with the following packages: Matplotlib (3.4.1), NumPy (1.20.2), Pandas (1.2.3), and SciPy (1.5.2).
For one-arm analysis of data, DataParty supports (but advises against) the meta-analysis of original proportions. For dichotomous data, DataParty includes 2 transformation functions: (1) logit and (2) arcsine square root. For data with original proportions, the logit transformation function is available. The inverse variance method is used for meta-analysis. The DerSimonian-Laird method is implemented for the random effects model.(1)
Meta-regression is performed with the logit function. Coefficients express the impact of the independent variable(s) on the logit of proportions. DataParty back-transforms the logit of proportions exclusively for visualization. For fixed effects, the inverse variance method is used. For the random effects model, DataParty implements a DerSimonian-Laird method of moments estimator.(2)
