Functional dataanalysis is a branch of statistics that analyzes data providing information about curves, surfaces or anything else varying over a continuum. The continuum is often time, but may also be spatial location, wavelength, probability, etc. The data may be so accurate that error can be ignored, may be subject to substantial measurement error , or even have a complex indirect relationship to the curve that they define. For example, measurements of the heights of children over a wide range of ages have an error level so small as to be ignorable for many purposes, but daily records of Precipitation meteorology precipitation at a weather station are so variable as to require careful and sophisticated analyses in order to extract something like a mean precipitation curve. However these curves are Estimation theory estimated , it is the assumption that they are intrinsically smooth that often defines a functional dataanalysis.

Multiple issues context January 2012 orphan February 2012 refimprove April 2011 no footnotes April 2011 Oversampling and undersampling in data analysis are techniques used to adjust the class distribution of a data set i.e. the ratio between the different classes categories represented . Oversampling and undersampling are opposite and roughly equivalent techniques. They both involve using a bias to select more samples from one class than from another. The usual reason for oversampling is to correct for a bias in the original dataset. One scenario where it is useful is when training a classifier using labelled training data from a biased source, since labelled training data is valuable but often comes from un representative sources. For example, suppose we have a sample of 1000 people of which 66 are male perhaps the sample was collected at a football match . We know the general population is 50 female, and we may wish to adjust our dataset to represent this. Simple oversampling will select each female example twice, and this copying will produce a balanced dataset of 1333 samples with 50 female. Simple undersampling will drop some of the male samples at random to give a balanced dataset of 667 samples, again with 50 female. clarify reason say why this is a good thing here or in general as throwing away data clearly loses information date April 2011 There are also more complex oversampling techniques, including the creation of artificial data points.
