Reconstruction errors are then measured by the cost function: (1) which adds up the squared distances between all the data points and their recon-structions. The weights summarize the contribution of the th data point to the th reconstruction. To compute the ...
Testing Normality of Data using SAS
lexjansen.comThe first step of data analysis usually involves making distributional assumption about the data. If the data is considered truly a sample from some classes of probability distributions, we cannot only summarize the data compactly based the approximate distribution, but also carry out proper statistical procedures to gain valuable inferences.

Inferential Statistical Tests Tests concerned with using selected sample data compared with population data in a variety of ways are called inferen-tial statistical tests. There are two main bodies of these tests.
