Produces Labour Market Areas from commuting flows available at elementary territorial units. It provides tools for automatic tuning based on spatial contiguity. It also allows for statistical analyses and visualisation of the new functional geography.

LAD (Least Absolute Deviations) estimation for linear regression, confidence intervals, tests of hypotheses, methods for outliers detection, measures of leverage, methods of diagnostics for LAD regression, special diagnostics graphs and measures of leverage. The algorithms are based in Dielman (2005)  <doi:10.1080/0094965042000223680>, Elian et al. (2000) <doi:10.1080/03610920008832518> and Dodge (1997) <doi:10.1006/jmva.1997.1666>. This package also has two datasets "houses" and "pollution", respectively, from Narula and Wellington (1977) <doi:10.2307/1268628> and Santos et al. (2016) <doi:10.1371/journal.pone.0163225>.

Lag-sequential analysis is a method of assessing of patterns (what tends to
follow what?) in sequences of codes. The codes are typically for discrete
behaviors or states. The functions in this package read a stream of codes,
or a frequency transition matrix, and produce a variety of lag sequential
statistics, including transitional frequencies, expected transitional frequencies,
transitional probabilities, z values, adjusted residuals, Yule's Q values,
likelihood ratio tests of stationarity across time and homogeneity across groups
or segments, transformed kappas for unidirectional dependence, bidirectional
dependence, parallel and nonparallel dominance, and significance levels based on
both parametric and randomization tests. The methods are described in
