Non-parametric Tests Unfortunately, it’s the first time that I learnt that Likert scale cannot be used together with t-test. According to my favorite Stat Wiki by Prof. Koji Yatani, Roughly speaking, there are two cases in which you want to use non-parametric test: Ordinal data: If your data are ordinal (like the results from Likert-scale…
PCA The main idea of PCA is to seek the most accurate data representation in a lower dimensional space. For a formal definition, according to Wikipedia, Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of…
P value is the probability that you are wrong if you reject the null hypothesis. or P value is the probability that you get equal or worse result if your experiment is right… or according to Wikipedia: For example, if you propose a hypothesis that Trump has more positive tweets than Hillary has, the your…

Windows Registry Editor Version 5.00
Next right click any image file -> property -> modify the default viewer -> find Windows Photo Viewer….
AtmoSPHERE In 2015, Kent, Max and I, together with our brilliant advisor Jon, made and published a sand-art project called AtmoSPHERE. It creates beautiful visualization of Kinect path-tracing data with a lego-built, customized XY table. Our Project Page is here: http://www.duruofei.com/Research/atmosphere Our Poster is here: http://www.duruofei.com/Public/poster/Du_AtmoSPHERE_poster_CHI2015.pdf Video: Sisyphus It turns out that our idea was not such a crazy idea…
This afternoon, I participated in the MSR Intern Fitness Group Training event. It was an one-hour exercise without break which enables us to work out almost every muscle in the body. First, rope jumping for 10min as a warm up. Next, jump grids. Ickey shuffle & Boogie Woogie & Sideways Skedaddle & Lateral High Step…
