sklearn_tutorial/04.1-Dimensionality-PCA.ipynb at master · jakevdp/sklearn_tutorial · GitHub
The dimensionality reduction might seem a bit abstract in two dimensions, but the projection and dimensionality reduction can be extremely useful when visualizing high-dimensional data. Let's take a quick look at the application of PCA to the digits data we looked at before:

How to read PCA plots — What do you mean "heterogeneity"?
To try to be concrete, we will consider 100 "genes", and throughout we will generate 600 "cells" from two "cell types". Different ways of generating these cell types will lead to different patterns in the PCA plot.

Bayesian Statistics the Fun Way | No Starch Press
This book will give you a complete understanding of Bayesian statistics through simple explanations and un-boring examples. Find out the probability of UFOs landing in your garden, how likely Han Solo is to survive a flight through an asteroid shower, how to win an argument about conspiracy theories, and whether a burglary really was a burglary, to name a few examples.

By using these off-the-beaten-track examples, the author actually makes learning statistics fun. And you’ll learn real skills, like how to:

How to measure your own level of uncertainty in a conclusion or belief
Calculate Bayes theorem and understand what it’s useful for
Find the posterior, likelihood, and prior to check the accuracy of your conclusions
Calculate distributions to see the range of your data
Compare hypotheses and draw reliable conclusions from them

A Bayesian view of Amazon Resellers | beta-binomial model
After observing 2 positive reviews, our posterior estimate on θB has a beta(3, 1) distribution. The probability that a sample from θA is bigger than a sample from θB is 0.713. That is, there’s a good chance you’d get better service from the reseller with the lower average approval rating.

Introduction — PyFlux 0.4.7 documentation
PyFlux is a library for time series analysis and prediction. Users can choose from a flexible range of modelling and inference options, and use the output for forecasting and retrospection. Users can build a full probabilistic model where the data y and latent variables (parameters) z are treated as random variables through a joint probability p(y,z). The advantage of a probabilistic approach is that it gives a more complete picture of uncertainty, which is important for time series tasks such as forecasting. Alternatively, for speed, users can simply use Maximum Likelihood estimation for speed within the same unified API.

International Nonresponse Trends across Countries and Years: An analysis of 36 years of Labour Force Survey data | Survey Methods: Insights from the Field (SMIF)
Household survey nonresponse is a matter of concern in many countries. In one of the first international trend analyses, de Leeuw and de Heer (2002) found that response rates declined over the years, and that countries differed in response rates and nonresponse trends. Their analyses cover longitudinal data on the Labour Force Survey from National Statistical Institutes for the period 1980 to 1997. We added a new data set, covering the period 1998 -2015, and analysed nonresponse data over time and countries. In these analyses we differentiated between voluntary and mandatory surveys. The trends visible in de Leeuw and de Heer (2002) continue with possibly a small deceleration in refusal rates.

Methods of Comparison, Compared

Log ratios are often used when considering growth, as with investment returns. For example, if a stock doubles and then halves, you’re back where you started: log⁡(21) log⁡(12)=0\log(\tfrac{2}{1}) \log(\tfrac{1}{2}) = 0log(12​) log(21​)=0. On the other hand if a stock goes up by fifty percent then down by fifty percent, you’ve lost twenty-five percent of your investment: (1×0.5)−(1.5×0.5)=−0.25(1 \times 0.5) - (1.5 \times 0.5) = -0.25(1×0.5)−(1.5×0.5)=−0.25. This is why log scales are commonly used in stock price charts, such as this change line chart and index chart.
