We first calculate the marginal effects by adding up the main effects and the interaction terms at the respective sample means (using the margin command in Stata). To estimate the unit change in ROA for a 1 % change in market share (ΔROA/ΔMSMS), we divide the respective marginal ...
The pooled weight mean difference (WMD) of MPV between the ITP group and hypo-productive group was analyzed using a random-effects model meta-analysis. Relevant data were extracted using a Microsoft Excel spreadsheet and analyzed using STATA 11.0 and Meta-disc 1.4 software. P...
