Presents procedure, mixed-radix positional number algorithm, for reducing set of numerous changes and stabilities in multiple roles at given time to a single empirical code. Demonstrates applicability and utility of procedure to wide array of complex family analyses through a simple pedagogical example. (Author/NB)

Asserts that, despite its growing popularity, there still exists confusion about the nature and proper use of logistic regression in family studies. Presents nontechnical discussion of logistic regression, with illustrations and comparisons to better-known procedures. Concludes that logistic regression can be powerful statistical procedure when…

Briefly describes core ideas behind LISREL (linear structural relationship) approach for studying structural models. Addresses some common issues with which family investigators deal, focusing on problems that researchers often face; questions they raise; and decisions they need to make in the process of model specification, estimation,…

Notes that conventional statistical models are not suited for analysis of nonindependent observations produced by family systems.

Built-in data structures are the registers and memory words where binary values are stored; hard-wired algorithms are the fixed rules, embodied in electronic logic circuits, by which stored data are interpreted as instructions to be executed. Various topics related to these two basic elements of every computer program are discussed. (JN)
