When using regression to calculate propensity scores, if the confounding variables do not balance, various transformations will be applied to any continuous confounding variables. If at any point the confounding variables achieve balance, the process ends and the current set of transformations...
Using the line equation to calculate unknown sample values So you now have the equation for the line. To determine unknown values based on this, so in this example it would be using background-corrected absorbance values for unknown samples (‘y’) to work out the total protein concentration...
The ongoing COVID-19 pandemic has highlighted the vast differences in approaches to the control and containment of coronavirus across the world and has demonstrated the varied success of such approaches in minimizing the transmission of coronavirus. Whil
A quick way to get the population mean and standard deviation! Okay, that may not seem like a big deal to you. The Stat function’s true time-saving power comes when you’re asked to look for standard deviation or variance in a slightly more complex question like this: ...
The standard deviation is the square root of the variance. Unfortunately, according to mathematical theory, you can’t do arithmetic operations with standard deviations, although you can with variances. A pooled standard deviation is just a weighted average of the standard deviation (variances) from...
A public health department wants to create a respiratory health risk index to highlight environmental injustices. To do this, the analyst can run theCalculate Composite Indextool multiple times to create an index with multiple subindices, in which the first run of the tool creates subindic...
000 equals the standard market risk of a diversified market-cap weighted global equity index. RiskGrades change over time to reflect not only the unsystematic risk of an investment but also increases in overall systematic risk in the market. RiskGrades are based on avariance-covariance approach...
To calculate alpha in a simple way, subtract the total return of an investment from a comparable benchmark in its asset category. To take into account asset investments that are not completely similar, calculate alpha usingJensen’s alpha, which uses the capital asset pricing model (CAPM) as ...
