MSIS 2014
1.1. Production of Official Statistics
( ffi i l) i i d i i l• (Official) Statistics production is a complex process, initiated by demand (data users), but constrained by resources (people & budgets)– In a National Statistical System, a number of govtoffices produce (official) statistics from primary data collection and/or compilation of data (even i t li d NSS)in a centralized NSS)
– Data sources: censuses, sample d i i t ti ti tsurveys, administrative reporting systems
– Quality and timeliness of statistics aggregates d d th d d li f d tdepend on methods, and suppliers of data.

• BIG DATA harnessed by businesses – Amazon uses customer database creatively: y
• “customers who bought Product A also bought Product B, Product C or Product D …” based on a predictive modeling (association rules and collaborative filtering)
– Social media, such as tweets on Twitter, are now examined in terms of “polarity” (i.e., positive, negative, or neutral) of expressed ( p g ) psentiments on a product, such as a movie.
– Public Wanting to “Know in (Real) Time”
