Al chemistry

ThIS pari describes the essentials of IlyperCdieni s theoretical and compiitaiion al chemistry or how IlyperCheni performs chemical calculations that yon request from the Setup and Compute menus. While it has pedagogical value, it isnot a textbook of computational chemistry the discussions are restricted to topics ol imme-diate relevance to IlyperChem only. Xeveriheless, yon can learn much about computational chemistry by reading this manual while using IlyperChem.

As discussed in the introduction, the solution of the inverse model equation for the regression vector involves the inversion of R R (see Equation 5 23). In many anal al chemistry experiments, a large number of variables are measured and R R cannot be inverted (i.e., it is singular). One approach to solving this problem is called stepwise MLR where a subset of variables is selected such that R R is not singular. There must be at least as many variables selected as there are chemical components in the system and these variables must represent different sources of variation. Additional variables are required if there are other soairces of variation (chemical or physical) that need to be modeled. It may also be the case that a sufficiently small number of variables are measured so that MIR can be used without variable selection.
