Predictive
pri-DIK-tiv
/prɪˈdɪktɪv/
Relating to or having the power to foretell the future.
In data science, 'predictive' refers to methods or models that use historical data to forecast future outcomes or probabilities, rather than simply describing past events.
The story behind the word. The word 'predictive' comes from the Latin 'praedicere', meaning 'to say beforehand, declare'. It's formed from 'prae-' (before) and 'dicere' (to say). So, something 'predictive' is literally 'saying before' it happens. It entered English in the 17th century, and its application to data models for forecasting became prominent in the late 20th century.
