The instantaneous maximum discharge is a hydrological parameter that can be estimated by deterministic, probabilistic and empirical models or direct instrumental measurements, however, their magnitudes are influenced equally by the The instantaneous maximum discharge is a hydrological parameter that can be estimated by deterministic, probabilistic and empirical models or direct instrumental measurements, however, their magnitudes are influenced equally by the morphometry of the catchment and its drainage network.
The methodology consisted of measurements and calculations of the morphometric parameters of the catchments and their drainage networks, and the use of multivariate statistical techniques linear correlation analysis, principal component analysis and multiple linear regression analysis.
It was considered as instantaneous maximum discharges for a return period of years those estimated by other authors. Most of the predictive models generated by each morphometric variable shows very good results in their estimates of the instantaneous maximum discharges of the catchments analyzed, however, only one was selected as the best predictor model best correlation coefficientswhich in this case is the corresponding variable basin scale. Regression analysis with compositional data containing zero values.
Multviariada analysis, for prediction purposes, with compositional data is multivariara subject of this paper.

We examine both cases when compositional data are either response or predictor variables. A parametric model is assumed but the interest A parametric model is assumed but the interest lies in the accuracy of estaxistica predicted values. For this reason, a data based power transformation is employed in both cases and the results are compared with the standard log-ratio approach. There are some interesting results and one advantage of the methods proposed here is the handling of the zero values.
Normal multivariada, contorno de probabilidade.
Typical load profiles of consumers and networks are essential information for determining the use rates in electric power distribution systems. It is noteworthy that the time of use tariffs are based on the hourly load profiles.

This paper presents a computational implementation in R environment of the K-Means, KMedoids and Ward methods, three multivariate statistical methods for cluster analysis, useful in identifying typical daily load profiles, a critical stage in the revision of electricity tariff. This paper provides an effective and economical alternative to the construction of typologies of load curves. Luiz da Costa Laurencel.
This article shows the main results of an analysis of the election for governor of the State of Rio de Janeiro in Initially, Simple Correspondence Analysis is applied to the data in order to reduce the problem dimension, multkvariada the Initially, Simple Correspondence Analysis is applied to the data in order to reduce the problem dimension, with the k-means technique used in sequence to obtain a clustering of more homogeneous counties.
It shows, not conclusively, how voters perform their choice of vote, which results in the clustering map. Multivariate data analysis in R.
