A statistical package is a kind of large computer program that is specialised for statistical analysis. It enables people to obtain the results of standard statistical procedures and statistical significance tests, without requiring low-level numerical programming. Most statistical packages also provide facilities for data management. // A computer program or software program (usually abbreviated to a program) is a step-by-step list of instructions written for a particular computer architecture in a particular computer programming language. ...

Specific Packages
http://www.cfmc.com (Market Research Software: WebCATI, Survent, Mentor, WebPM, for information about Mentor)
Statistical methods for estimating population parameters and their associated variances are based on assumptions about the characteristics and underlying distribution of the observations.
Packages should have the capacity to handle nonstandard designs, or provide guidance in the documentation as to the most appropriate design to specify in these circumstances and what the consequences are (such as an overestimate of the variance).
Depending on the specialized package and the estimates desired, it may be necessary to then take the output from the specialized package and carry out further data manipulation in the original general-purpose (or yet another) statisticalpackage to obtain the needed estimates.
