grand_mean_center

Compute grand-mean centered variables.
Usually used for GLM interaction-term predictors and HLM level-2 predictors.

Broadly useful convenient and efficient R functions
that bring users concise and elegant R data analyses.
This package includes easy-to-use functions for
(1) basic R programming
(e.g., set working directory to the path of currently opened file;
import/export data from/to files in any format;
print tables to Microsoft Word);
(2) multivariate computation
(e.g., compute scale sums/means/... with reverse scoring);
(3) reliability analyses and factor analyses;
(4) descriptive statistics and correlation analyses;
(5) t-test, multi-factor analysis of variance (ANOVA),
simple-effect analysis, and post-hoc multiple comparison;
(6) tidy report of statistical models
(to R Console and Microsoft Word);
(7) mediation and moderation analyses (PROCESS);
and (8) additional toolbox for statistics and graphics.
