Surveys are a valuable way to get feedback from customers, employees or research respondents. Learn more about surveys and use our FREE tool here.
Learn what the differences are between type 1 and type 2 errors in statistical hypothesis testing and how you can avoid them.
Surveys and standard errors are crucial parts of probability theory and statistics. Statisticians use standard errors toconstruct confidence intervalsfrom their surveyed data. Confidence intervals are important for determining the validity of empirical tests and research. The reliability of estimates can also...
Liquidity risk: While arbitrageurs provide market liquidity, they are susceptible to liquidity risk. Slippage in trades can occur, making it difficult for the arbitrageur to close out positions on time, potentially causing losses. Model risk: As the LTCM example above showed, statistical arbitrage in...

The sum of all of the residuals should be zero. In practice sometimes this sum is not exactly zero. The reason for this discrepancy is that roundoff errors can accumulate. Uses of Residuals There are several uses for residuals. One use is to help us to determine if we have a data set...
need. For example, the calculation is different for the mean or proportion. When you are asked to find the sample error, you’re probably finding the standard error. That uses the following formula: s/√n. You might be asked to find standard errors for other stats like...
Once identified, outliers can be included or omitted depending on how extreme they are and what statistical methods are being used in an analysis. Fix Structural Errors: It’s important to correct errors and inconsistencies including typography, capitalization, abbreviation, and formatting. Look at ...
