Create an ungrouped or grouped frequency tablefor an ordinal or quantitative variable. Cumulative frequencies don’t make sense for nominal variables because the values have no order—one value isn’t more than or less than another value. Add a third column to the table for the cumulative freque...
integral theorem, the conditions are satisfied on [−∞, +∞]: (1) the Dirichlet condition is satisfied on any interval; (2) if it is absolutely integrable on [−∞, +∞], that is, ∫−∞∞|f(t)|dt reaches convergence, then there is a Fourier integral formula, as shown in ...
The foods consumption was calculated using the following formula: frequency multiplied by the quantity of the foods in the corresponding food items. As for the individual daily nutrient intake, we established eight converted FFQ FCTs based on professional knowledge, representative 24HRs data, or the ...
The RFM model allows you to analyze historical transactional data and use this quantitative research to identify different types of customers and group them into segments based on their purchase history. RFM specialists initially use it in database marketing and direct marketing, but lately, RFM Anal...
