If you specify the option METHOD=SEQ and do not include a SIZE statement, PROC SURVEYSELECT uses the equal probability version of Chromy's method for sequential random sampling. This method selects ...

If you specify the option METHOD=PPS_SEQ, PROC SURVEYSELECT uses Chromy's method of sequential random sampling. Refer to Chromy (1979) and Williams and Chromy (1980). Chromy's method selects units ...

Coherent interleaved sampling is a new technique that can acquire data faster with more data points than sequential sampling. Engineers who need to characterize semiconductor devices, high-speed ...

Sequential estimation comprises a class of statistical techniques in which data are evaluated as they are collected and sampling is terminated according to a predefined rule rather than a fixed sample ...

Tektronix has announced the DSA8200 digital serial analyzer sequential-sampling oscilloscope, new remote-sampling electrical modules, and enhanced IConnect software for serial-data-network analysis.

With the introduction of the WaveExpert 9000 and SDA 100G, LeCroy Corp joins Agilent (www.agilent.com) and Tektronix (www.tektronix.com) in offering scopes in a category that used to be called ...
