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.

ESRA | Deliverables & publications

9 weeks ago by lena

ESRA (E-SURVEY OF ROAD USERS’ ATTITUDES) is a joint international initiative of 26 research centres and road safety institutes; the project has surveyed road users in 38 countries on 5 continents. The purpose of this network is to collect comparable data on the opinions, attitudes, and behaviour of road users concerning road safety and mobility, and to provide scientific evidence for policy making at the national and international levels. Vias institute initiated the project, and the first edition of the ESRA survey was launched in 2015. The institute continues to coordinate this fast-evolving endeavour, and the next edition will be in 2018.

Emulating R plots in Python – A Journey in Data

10 weeks ago by lena

One of the simplest R commands that doesn’t have a direct equivalent in Python is plot() for linear regression models (wraps plot.lm() when fed linear models). While python has a vast array of plotting libraries, the more hands-on approach of it necessitates some intervention to replicate R’s plot(), which creates a group of diagnostic plots (residual, qq, scale-location, leverage) to assess model performance when applied to a fitted linear regression model.

Practical Guide to Cluster Analysis in R (book)

11 weeks ago by lena

Although there are several good books on unsupervised machine learning/clustering and related topics, we felt that many of them are either too high-level, theoretical or too advanced. Our goal was to write a practical guide to cluster analysis, elegant visualization and interpretation.

The main parts of the book include:

distance measures,

partitioning clustering,

hierarchical clustering,

cluster validation methods, as well as,

advanced clustering methods such as fuzzy clustering, density-based clustering and model-based clustering.

Summated Rating Scale Construction | SAGE Publications Ltd

june 2018 by lena

$20 ebook, was recommended by statistician.

The goal for any social scientist doing a survey is to develop a rating on some attitude, value or opinion - a summated rating scale. Aimed at helping researchers construct more effective scales, Spector shows how to determine the number of items necessary, the appropriate amount of response categories and the most productive wording of items, how to sort good items from bad (including item-remainder coefficients and Cronbach's alpha) and how to validate a scale, including dimensional validity from factor analysis. Written in a user-friendly manner, the book concludes with a step-by-step account of how to develop a summated rating scale based on classical test theory.

Uses of the logarithm transformation in regression and forecasting

june 2018 by lena

Change in natural log ≈ percentage change: The natural logarithm and its base number e have some magical properties, which you may remember from calculus (and which you may have hoped you would never meet again). For example, the function eX is its own derivative, and the derivative of LN(X) is 1/X. But for purposes of business analysis, its great advantage is that small changes in the natural log of a variable are directly interpretable as percentage changes, to a very close approximation. The reason for this is that the graph of Y = LN(X) passes through the point (1, 0) and has a slope of 1 there, so it is tangent to the straight line whose equation is Y = X-1 (the dashed line in the plot below):

Is two-tailed testing for directional research hypotheses tests legitimate? - ScienceDirect

may 2018 by lena

This paper demonstrates that there is currently a widespread misuse of two-tailed testing for directional research hypotheses tests. One probable reason for this overuse of two-tailed testing is the seemingly valid beliefs that two-tailed testing is more conservative and safer than one-tailed testing. However, the authors examine the legitimacy of this notion and find it to be flawed. A second and more fundamental cause of the current problem is the pervasive oversight in making a clear distinct...
