Why Is It So Hard to Define Software Architecture?

In recent years, software engineering researchers have elevated the study of software architecture to the level of a major area of study. A review of the published literature however, shows quite clearly that a unified view of software architecture has not been forth-coming. This paper contends that the existence of a "software architecture level of design" is based on the implicit assumption t...

Why Is It so Hard to Estimate Expected Returns?

A key part of experiment design is determining how much data to collect. When the data comes in the form of a timeseries, the sample size is expressed both by the count N of the observations and the duration T of the historical period over which observations were made. For forecasting the drift of an asset price process with continuous sample paths, it turns out that the duration is key. I demo...
