If a liver FF of ≥6.1% on MRS was used to denote hepatic steatosis, sensitivity, specificity, and positive and negative predictive values (adjusted for the portion of the whole study cohort receiving each grading) of ultrasound in detecting "definite steatosis" were 86.8%, 100%, 100%, and 80.0%, respectively.
WEKA does not enable output of the 10-fold cross-validation data itself, so to obtain these data for proteins in our training set, we randomly split our training set into 10 portions of roughly equal size (within 10%) and use 9 of the ten portions to train the RF, which was then used to produce values for the tenth portion.
The equivalent values for the Egyptian portion of the lake, Lake Nasser, are 2 585 km2 and 5 248 km2.
For muscles in scans A and B, the peak CT values for the stained portions varied in different regions of the head (Figs. 3-a, b and 5-a, b).
The value of the portion is denoted by seed_ration.
The stronger optical depth enhances the stratospheric upward flux increase such that the upward flux surpasses its surface value for the central portion of the 667 cm−1 CO2 band (from about 640 to 690 cm−1).
Nutrient intakes were computed for each subject by assigning a weight proportional to the frequency of use of each food, multiplying this weighting by the nutrient value for the specified portion size, and summing the contributions of all foods.
We calculated the average ST-segment level, referenced to the P-R isoelectric values, for each portion of the protocol.
Custom algorithms were created to calculate the average "ST-segment level" or value, referenced to the P-R isoelectric values, for each portion of the protocol.
A potentially important limitation of this analysis includes the use of imputed values for a portion (∼24%) of inhalation exposure.
