What is a multicollinearity?Understanding multicollinearity can be easier if you learn about the contexts and projects where it commonly occurs. In statistical analysis, multiple regression is a method used to
Multivariate Testing (MVT) is a statistical method used to test multiple variables on a webpage or app simultaneously to find the best combination for a specific goal, such as increasing conversions or improving user engagement. Multiple elements are tested together to understand how they interact a...
Dichotomous are the simplest possible variables.The point here is that -given the sample size- thefrequency distributionof a dichotomous variable can be exactly described with a single number: if we've 100 observations on sex and 45% is male, then we know all there is to know about this va...
