JSS上面新发表了一篇文章,我大致看了一下,觉得还挺有意思,和大家分享一下:
SOCR Analyses: Implementation and Demonstration of a New Graphical Statistics Educational Toolkit
以下是摘要:
The web-based, Java-written SOCR (Statistical Online Computational Resource) tools
have been utilized in many undergraduate and graduate level statistics courses for seven
years now (Dinov 2006; Dinov et al. 2008b). It has been proven that these resources
can successfully improve students' learning (Dinov et al. 2008b). Being rst published
online in 2005, SOCR Analyses is a somewhat new component and it concentrate on data
modeling for both parametric and non-parametric data analyses with graphical model
diagnostics. One of the main purposes of SOCR Analyses is to facilitate statistical learn-
ing for high school and undergraduate students. As we have already implemented SOCR
Distributions and Experiments, SOCR Analyses and Charts fulll the rest of a standard
statistics curricula. Currently, there are four core components of SOCR Analyses. Linear
models included in SOCR Analyses are simple linear regression, multiple linear regression,
one-way and two-way ANOVA. Tests for sample comparisons include t-test in the para-
metric category. Some examples of SOCR Analyses' in the non-parametric category are
Wilcoxon rank sum test, Kruskal-Wallis test, Friedman's test, Kolmogorov-Smirno test
and Fligner-Killeen test. Hypothesis testing models include contingency table, Friedman's
test and Fisher's exact test. The last component of Analyses is a utility for computing
sample sizes for normal distribution. In this article, we present the design framework,
computational implementation and the utilization of SOCR Analyses.
