Webb23 mars 2012 · Abstract. One of the often-stated goals of principal component analysis is to reduce into a low-dimensional space most of the essential information contained in a high-dimensional space. According to several reasonable criteria, principal components do this optimally. From a practical point of view, however, principal components suffer from … WebbThe principle variables of metamorphism are: Heat and pressure If the carbon dioxide had not been removed from the early atmosphere, Earth's climate would most closely … WebbAll of these factors vary widely and result in different types of metamorphism depending upon which factor is dominant.
