6.!The LIBNAME Statement - Permanent SAS Data Set SAS stores data as "SAS data set" (.sas7bdat). There are 2 types of SAS data sets: temporary and permanent. Temporary dataset exists only during the current job and is erased when exit SAS. It has an one- T he normal or Gaussian (parametric) distribution is one. of the most studied types of distribution in biostatistics. It is defined. by two parameters: mean (ì) and variance (ó²). Among its sciences, then we use the term biostatistics. Populations: A population is the largest group of people or things in which we are interested at a particular time and about which we want to make some statements or conclusions. Samples: From the population, we select various elements (or individuals) on which we collect our information. Basic concepts, importance of Biostatistics & SAS.
