an estimate (m) is used based upon a statistic such as the arithmetic or geometric mean of past returns. 3. Problems with estimates of the expected return To investigate the properties of the arithmetic mean and geometric mean of past returns as estimators of the discount rate, we assume that annual total return
Regular digital thermometers use electronic heat sensors to record body temperature. These thermometers can be used in the rectum, mouth or armpit. Armpit temperatures are usually the least accurate. Rectal temperatures provide the best readings for infants, especially those 3 months or younger, as well as children up to age 3. For older children and adults, oral readings are usually accurate â as long as the mouth is closed while the thermometer is in place.
