Inked Sadness is a collection of poems written in that difficult time between being no longer young, but not yet old.
Expressions and Conversations of Love are short heart-breakers.
Proverbial Man considers how our names and expectations limit our perceptions and freedoms. No answers are offered. I don't think I finished this.
The Surrogate echoes my own fears of fleeing from Poland in the early 80s. Or at least the fears I retroactively erected, to add drama. Count on the Polish for drama.
Thirty Reasons should be enough to decide a place isn't worth returning to.
By my friend and colleague Emanuele Raffaele Ettore Libertini, the NeverEnder is a voyage through space and words.
Some outliers influence the regression fit more than others.
This month our column addresses the effect that outliers have on linear regression.
You may be surprised, but not all outliers have the same influence on the fit (e.g. regression slope) or inference (e.g. confidence or prediction intervals). Outliers with large leverage—points that are far from the sample average—can have a very large effect. On the other hand, if the outlier is close to the sample average, it may not influence the regression slope at all.
Quantities such as Cook's distance and the so-called hat matrix, which defines leverage, are useful in assessing the effect of outliers.

Celebrate `\\pi` Day (March 14th) with colliding digits in space. This year, I celebrate the detection of gravitational waves at the LIGO lab and simulate the effect of gravity on masses created from the digits of `\\pi`.
Some strange things can happen.
Use alignment and consistency to untangle complex circuit diagrams.
This month we apply the ideas presented in our column about drawing pathways to neural circuit diagrams. Neural circuits are networks of cells or regions, typically with a large number of variables, such as cell and neurotransmitter type.
We discuss how to effectively route arrows, how to avoid pitfalls of redundant encoding and suggest ways to encorporate emphasis in the layout.
