A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

TRAC TRENDS IN ANALYTICAL CHEMISTRY

The polar coordinates projection (PCP) method consists in plotting samples as the center of gravity of the data values expressed in polar coordinates. Results obtained when applying this technique to several data sets show that PCP, which is computationally simpler than other data-reduction techniques, can be used to obtain an informative graphical representation of multidimensional data, sometimes as informative as principal component analysis.
