[NEAS: We provide illustrative Excel work-sheets for the statistical techniques that are not available as built in functions or add-ins. The SOA wants to ensure all candidates can use some statistical software, such as Excel, SAS, Minitab, "R," etc. For an actuarial career, it is worth learning the basic Excel functions. See the Excel on-line help, tutorials, users' guides, and manuals, or find another worker who has used Excel.]
