: In research regarding "sub-zip shifts of finite type," the term LM-zip shift is used to describe an extension of topological Markov chains and Bernoulli transformations.
: The file name LM.zip has appeared in public disclosure logs, such as those from the San Francisco Sunshine Ordinance Task Force , though these typically represent internal administrative data rather than public software. lm.zip
: Used when derivatives are unknown or difficult to calculate, requiring the algorithm to use finite differences instead. : In research regarding "sub-zip shifts of finite
The lm.zip package is a translation of the original routines, specifically LMDER and LMDIF , into modern Fortran. It is frequently hosted in specialized mathematical software repositories such as Alan Miller's Fortran Software . The lm
: Designed for functions where the user can provide explicit derivatives (Jacobians).
: The archive typically includes the original MINPACK test programs and a practical example demonstrating a fit for a 4-parameter logistic model . Broader Contexts
While most commonly associated with scientific computing, the term appears in a few niche academic or administrative contexts:
