+\details{
+The data was taken from the book [1] and is in fact a small subset of a pan-European demographic survey. It includes information about 32 persons, 16 represent northern Europe (Scandinavians) and 16 are from the Mediterranean regions. In both groups there are 8 male and 8 female persons. The data includes both quantitative and qualitative variables and is particularly useful for benchmarking exploratory data analysis methods.

+Spectral data of polyaromatic hydrocarbons mixing

+\description{
+Simdata contains training and test set with spectra and concentration values of polyaromatic hydrocarbons mixings.
+}
+
+\usage{data(simdata)}
+\format{
+   The data is a list with following fields:
+   \tabular{rlll}{
+    \code{$spectra.c} \tab a matrix (100x150) with spectral values for the training set. \cr
+    \code{$spectra.t} \tab a matrix (100x150) with spectral values for the test set. \cr

+  }
+}
+
+\details{
+This is a simulated data containing UV/Vis spectra of three component (polyaromatic hydrocarbons) mixings - C1, C2 and C3. The spectral range is betwen 210 and 360 nm. The spectra were simulated as a linear combination of pure component spectra plus 5\% of random noise. The concentration range is (in moles): C1 [0, 1], C2 [0, 0.5], C3 [0, 0.1].
+
+There are 100 mixings in a training set and 50 mixings in a test set. The data can be used for multivariate regression examples.
