what are packages? R packages are collections of code, data, and documentation that extend R’s functionality beyond its core features. If you have an idea or notice a gap in the existing ecosystem, you can develop a package, test it, document it, and share it with the broader R community. You can distribute your package through the Comprehensive R Archive Network (CRAN) 1 (CRAN) or GitHub.
Memorization “The main reason to memorize the Bible is not to accumulate more data in our brains. It’s a way for us to enjoy God” - Andy Naselli I’ve started to memorize big chunks of the Bible with a group of men at church, and this has been both, challenging and amazing. Somehow, I feel more ready for the day when I bring scripture to the forefront of my mind.
not so quickly! Recently, I become intrigued by game theory algorithms, not because I absolutely love playing games, but because it offers a quantifiable, systematic way to understand human relationships. I find the certainty of science and systematization reassuring to some degree so when I learned about this game called “the prisoner’ dilemma”, I thought it would fun to experiment and figure out the answer to this classic scenario.
monthly changes in her circle orb Tip If you’re wondering where I’m getting my titles and headings, they come from Shakespeare’s sonnets. The moon has always fascinated me. Eversince I was a child, I was entranced by it; her constant pursuit everywhere I went and her sneaky tactics during the day. This year, before the solar eclipse, I decided to do a little digging and replicate one algorithm used to determine the phases of the moon.
Visualization & Pearson’s correlation coefficient The 30DayChartChallenge is a data visualization community that hosts daily challenges for April. Today’s challenge involves dinosaurs. I used the Datasaurus package to create an animated visualization to demonstrate the importance of graphing data, and the effects of outliers on statistical properties.
Lissajous Curves Lissajous curves are created by plotting two oscillations on perpendicular axes and . These oscillations, represented by sinusoidal functions, intersect to create different patterns. When the ratio of these frequencies is equal to — the oscillations are equally phased— the curve is a straight line.
TL; DR: Don’t be an absolutist– use relative paths. Use the here package instead of setwd() or getwd() to increase reproducibility and avoid wasting your and other people’s time.
RQ: What exactly is the CLT and what’s the deal with n 30? CLT - mathematical definition and simple terms definition How we use CLT How to know when empirical distribution converges to normal distribution? How did we come up with n $ $ 30? Cohen (1991) Taught that at least 30 observations were needed to use critical-ratio approach used in t-tables when comparing groups.
Quantile Beta Regression The quantile beta regression model discussed in the 2021 paper by Running Code When you click the Render button a document will be generated that includes both content and the output of embedded code.
