GROSS ALPHA AND GROSS BETA RADIOACTIVITY IN DRINKING WATER METHOD 900.0. 1.0. Scope and Application. 1.1. This method covers the measurement of gross alpha and gross beta particle activities in drinking water. The method is a screening technique for monitoring drinking water supplies for alpha and beta particle activities according to the limits set forth under the Safe Drinking Water Act, PL.

Alpha and Beta Risks Alpha Risk. Alpha risk is the risk of incorrectly deciding to reject the null hypothesis. If the confidence interval is 95%, then the alpha risk is 5% or 0.05. For example, there is a 5% chance that a part has been determined defective when it actually is not. One has observed, or made a decision, that a difference exists but there really is none. Or when the data on a.

Glossary; Whittaker (1972) described three terms for measuring biodiversity over spatial scales: alpha, beta, and gamma diversity. Alpha diversity refers to the diversity within a particular area or ecosystem, and is usually expressed by the number of species (i.e., species richness) in that ecosystem.For example, if we are monitoring the effect that British farming practices have on the.We review the problem of fractional statistics as it applies to two current areas of interest in condensed-matter physics: the fractional quantum Hall effect (FQHE), and high-temperature superconductors (HTSC). In the case of the former, we emphasize Haldane's recent definition (1991) of a fractional exclusion principle, and show a relation between this idea and the standard definition of.Understanding the beta distribution (using baseball statistics) Note: I originally published a version of this post as an answer to this Cross Validated question. Some distributions, like the normal, the binomial, and the uniform, are described in statistics education alongside their real world interpretations and applications, which means beginner statisticians usually gain a solid.

Power in the context of biostatistics is defined as 1 - beta or the probability that you will not reject the null hypothesis when in fact the alternative hypothesis is true (i.e., making a type II error).

Read MoreIn addition to alpha and beta, a third MPT statistic is R-squared. R-squared measures the strength of the relationship between excess returns on the benchmark and excess returns on the fund being analyzed. MPT statistics are calculated from a comparison of a fund’s excess returns and the benchmark’s excess returns. Unless a time horizon is.

Read MoreHow do I calculate alpha (scale) and beta (shape) for a Weibull distribution? Close. 3. Posted by 4 years ago. Archived. How do I calculate alpha (scale) and beta (shape) for a Weibull distribution? I am replicating an analysis and everything seems straight forward but the values for shape and scale are value-ed out instead of formulas. Any help would be greatly appreciated. Thanks! 6.

Read MoreAfter the evaluation of the F-value and R 2, it is important to evaluate the regression beta coefficients. The beta coefficients can be negative or positive, and have a t-value and significance of the t-value associated with each. The beta coefficient is the degree of change in the outcome variable for every 1-unit of change in the predictor variable. The t-test assesses whether the beta.

Read MoreAlpha and Beta are the two positive parameters of the beta distribution whose value lies between 0 and 1 and are used for controlling the shape of distribution by modification in its values.

Read MoreAlpha and beta are two common measurements of investment risk. However, I must add a caveat before we jump in. Alpha and beta are part of modern portfolio theory, much of which is questioned by analysts (including myself). That doesn’t mean you can’t use the concepts of alpha and beta to have a better understanding of investing. First we will examine Alpha and beta. Then we will look at.

Read MoreAlpha, beta, gamma rays: It almost sounds like the tagline of an old-school motion picture about aliens from outer space, newly arrived on Earth with their ultra-high-tech gadgets (and hopefully a warm disposition).In reality, this isn't too far off. Alpha, beta and gamma radiation are all real entities in the physics world and are worth avoiding when you can manage it.

Read MoreThe beta distribution has nothing to do with any of the other uses of the term beta. Other uses of Alpha and Beta. If you really start to get into higher level statistics, you’ll see alpha and beta used quite often as parameters in different distributions. I don’t know if they’re commonly used simply because everyone knows those Greek.

Read MoreAlpha measures a mutual fund manager’s or strategy's effectiveness. It shows the difference between a fund's actual returns and its expected performance, given its level of risk as measured by beta.
