oliveoil

This data set represents eight chemical measurements on different specimen of olive oil produced in various regions in Italy (northern Apulia, southern Apulia, Calabria, Sicily, inland Sardinia and coast Sardinia, eastern and western Liguria, Umbria) and further classifiable into three macro-areas: Centre-North, South, Sardinia.

Provides tools to work with the Flexible Dirichlet
distribution. The main features are an E-M algorithm for computing the maximum
likelihood estimate of the parameter vector and a function based on conditional
bootstrap to estimate its asymptotic variance-covariance matrix. It contains
also functions to plot graphs, to generate random observations and to handle
compositional data.

oliveoil function

This data frame contains 572 rows, each corresponding to a different specimen of olive oil, and 10 columns. The first and the second column correspond to the macro-area and the region of origin of the olive oils respectively; here, the term &#39;region&#39; refers to a geographical area and only partially to administrative borders. Columns 3-10 represent the following eight chemical measurements on the acid components for the oil specimens: palmitic, palmitoleic, stearic, oleic, linoleic, linolenic, arachidic, eicosenoic.
