 The number of problems and therefore the range of disciplines where the collected data are curves is recently increasing. Such curve data could also be generated by densely spacetime repeated measurements, or by automatic recordings of a quantity of interest. Since beginning of the nineties, Functional Data Analysis (FDA) is employed so as to model this sort of data . Since the pioneer work by Deville (1974), and all the more as of late with the work by Ramsay and Silverman (2005), the factual network has demonstrated an expanding enthusiasm for creating models for useful information. Practical variants for a decent scope of factual instruments are given.Tests of such techniques incorporate exploratory and unmistakable information investigation (Ramsay and Silverman, 2005), direct models (Cardot et al, 1999; Ramsay and Silverman, 2005), non-parametric strategies (Ferraty and Vieu, 2006) or multivariate techniques (Silverman, 1995; Ferraty and Vieu, 2003). In applied sciences, it's common that data have both spatial and functional components. In agronomy, as an example , previous to the crop, measures of penetration resistance are taken during a sampling grid of the study area (Chan et al., 2006). during this case, and though penetration resistance is measured only in some depths, it's possible to think about it as a functional variable after a smoothing or interpolation process are applied. Other examples are given when daily cycles of oxygen are measured in several points of a study zone (Mancera and Vidal, 1994) or when curves of temperature or precipitation are obtained in several weather stations of a rustic (Ramsay and Silverman, 2005).
