Robust statistical approach for small sample research (April 2018)
1. Data set (from 27 Japanese language learner)
2. OxGauss Codes (Ordinary Least Squares (OLS) analysis)
3. OxGauss Codes (Bootstrap Ordinary Least Squares (Bootstrap OLS) analysis)
4. OxGauss Codes (Quantile regression (QS) analysis)
5. OxGauss Codes (Bootstrap Quantile Regression (Bootstrap QS) analysis)
6. Original paper (PDF).
Notes: the findings in the paper are based on R-programming analysis, rather than OxGauss programming analysis. Thus, there are some discrepancies between the former and the latter analysis. However, difference in findings are fairly minor.
The Baron – Kenny method
7. Data set (Language learning motivation, attitude and stereotype: Japanese and Korean language)
8. Estimation of Total effect, Direct effect and Indirect effect (Sobel methods) first-order and second-order delta solution for the standard error estimation
9. Estimation of Indirect effect (Hayes method) Bootstrapped methods.
