Nineteen Ways of Looking at Statistical Software

New ways of looking at experimental phasing.

In the original work by Blow and Crick, experimental phasing was formulated as a least-squares problem. For good data on good derivatives this approach works reasonably well, but we now attempt to extract more information from poorer data than in the past. As in many other crystallographic problems, the assumptions underlying the use of least squares for phasing are not satisfied, particularly ...

New ways of looking at old issues: inequality and growth

Ž . The paper uses new cross-country data on income and asset land distribution to show Ž . that i there is a strong negative relationship between initial inequality in the asset Ž . distribution and long-term growth; ii inequality reduces income growth for the poor, but Ž . not for the rich; and iii available longitudinal data provide little support for the Kuznets hypothesis.

Lecture 1 “ 13 ways of looking at a random variable ”

0. Some Obligatory Formalism It is customary to begin with some priestly incantations about Kolmogorov’s axiomatic treatment of probability. We will keep this brief, since it won’t play a large role in subsequent developments. It is essential at some stage however since it is what really makes probability a proper branch of mathematics. In the beginning, before the chaos, there was the probabil...
