Chapter 7 Sampling and Sampling Distributions
... o Formulas are available for combining the stratum sample results into one population parameter estimate. o Advantage: If strata are homogeneous, this method is as “precise” as simple random sampling but with a smaller total sample size. Example: The basis for forming the strata might be department, ...

... There is a slight rounding error in these sums, but they should be good enough. The probabilities on the table are, as far as the present problem is concerned, conditional probabilities. For example, P 1 head w 3 .3750 . To allow for the die, multiply the column sums by 1 6 . ...

Data Summarization Methods in Base SAS Procedures
... QMETHOD=P2 is based on the piecewise-parabolic (P²) algorithm developed by Jain and Chlamtac (1985). P² is a onepass algorithm that is more efficient for large data sets because it requires a fixed amount of memory for each level within the type of each variable. However, based on simulation studies ...

... ‘Case Processing Summary’. It lists the number of cases in each of the two groups (F=Far and N=Near) defined by PROXIM. It also shows how many values in each group are missing - in other words how many have unknown values of PEFR. It often happens that not all data in a study are recorded for each i ...
