Deviation of Gain Calculator - agrimetsoft.com
Deviation of Gain. In contrast to R2, there are no significant problems in computing the average DG for periods comprising several years. The coefficient of gain from the daily mean, DG, compares model results with daily mean discharge values, which vary throughout the year. DG can vary between 0 and 1, with 0 being a perfect model (WMO, 1986).

Normalized gain: What is it and when and how should I …
Mar 18, 2016 · It normalizes the average raw gain in a population by the standard deviation in individuals’ raw scores. d = ( <post> - <pre> ) / stdev The major mathematical difference between normalized gain and effect size is that normalized gain does not account for the size of the class or the variation in students within the class, but effect size does.

Gain - Teledyne Photometrics
The mean divided by the variance equals the gain: gain = mean /variance. A more rigorous method is that of Mortara and Fowler ( SPIE Vol. 290 Solid State Imagers for Astronomy (1981) pp. 28-33), which essentially involves repeating the above procedure for a series of illumination levels over the full range of the CCD full well.

What does it mean when an investment has a high downside deviation?
Standard deviation measures volatility on the upside and the downside, which presents a limited picture. Two investments with the same standard deviations are likely to have different downside deviations. Downside deviation can also tell you when a "risky" investment with a high standard deviation is likely safer than it looks.

Which is the best way to calculate downside deviation?
The Sortino ratio says that the second one is better, and it quantifies the difference. The first step of calculating the downside deviation is to choose a minimum acceptable return (MAR). Popular choices include zero and the risk-free T-bill rate for the year. We'll just use one here for simplicity.

How to calculate the gain of an image?
A simple method to calculate the system gain is shown below: Collect a bias image (zero-integration dark image) and label it “bias”. Collect two even-illumination images and label them “flat1” and “flat2”. Calculate a difference image: diff = flat2 – flat1. Calculate the standard deviation of the central 100 x 100 pixels in the difference image.

How to calculate the normalized gain of averages?
Gain of averages: First calculate the average pre-test and average post-test score for your class, then take the normalized gain of these: <g> = (<Post> - <Pre>)/(100 - <Pre>) Average of gains: First calculate the normalized gain for each student, then average these: g ave = <(Post - Pre)/(100 - Pre)>.
