What does MAD stand for?

The widely used Carrier correlation has a mean absolute deviation of 136% and an average deviation of +132%.

The mean absolute deviation is a measure of the average error of the model.

Mean absolute deviation ([double dagger]) Average deviation COMPARISON OF CORRELATION WITH DATA The data listed in Tables 1 and 2 were compared to the present correlation.

Among the several ranking or selection criteria advocated in the finance literature, the semi-variance, mean absolute deviation of return, coefficient of variation, and mean-variance are frequently cited.

Four particularly popular measures of forecast error are: * Residual Error * Mean Absolute Deviation Error * Mean Absolute Percentage Error; and, * Mean Squared Error Simple forecast error or the residual is computed by subtracting the forecasted value from the actual value.

The mean absolute deviation (MAD) of predicted bed elevations from measured bed elevations was 0.

Treasury issues on the date of sale (the Treasury issues are neither due nor callable in less than ten years and are taken from the Moody's Bond Survey), a measure of the recent volatility of interest rates (it is determined as the mean absolute deviation in long-maturity Treasury rates over the 20 days preceding the sale date of the issue as reported in Moody's Bond Survey), the natural logarithm of the size of the issue measured in thousands of real 1976 dollars as deflated by the implicit GNP deflator, and a zero-one variable indicating that the issue was competitively bid (1) or negotiated (0).
