WebbThe sequential probability ratio test (SPRT) is a specific sequential hypothesis test, developed by Abraham Wald [1] and later proven to be optimal by Wald and Jacob Wolfowitz. [2] Neyman and Pearson's 1933 result inspired Wald to reformulate it as a sequential analysis problem. The Neyman-Pearson lemma, by contrast, offers a rule of … WebbAM1880 Standard Platinum Resistance Thermometers (SPRT) interpolates temperature in the range from -200 °C to 670 °C on the International Temperature Scale of 1990 (ITS …
