I think this work is really exciting, and I also want to refer readers to this 2014 paper by Kaniav Kamary, Kerrie Mengersen, Christian Robert, and Judith Rousseau, "Testing hypotheses via a mixture estimation model." (I don't like the testing hypothesis part but I like the way they set up an artificial mixture model.)

Get PriceAll mediums and aggregates are local: Although various norming standards for mediums have been defined (ASTM, US DOT, DIN, ANSI, etc.), those norm/standards are only rough averages: they are specific definitions of terms used in contract specifications sheets, architectural or engineering detail sheets, geotechnical designs, and so forth.

Get PriceUsing Weights in Data Analysis we can use weight variables to adjust sample statistics to represent population statistics. • If sample is selected with a probability sampling method, the data sets should have weight variables including probability weight, primary sampling units (PSU), strata, and finite population correction (FPC).

Get PriceAggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel.
