A What you are talking about is nothing, but general the 52、ory of relativity.B It is a stupid question, my first-year graduate student can answer that.C I have just talked about that, why did you ask such a question again.D It is really a good question, thanks for your asking....
Quantitative methods involves collecting and analysis of the numerical data helping to find patterns, correlation & trends within that data.
The bookstore opts for K-means clustering for the ‘average spend per visit’ variable because it’s numerical – and therefore scalar data. For ‘favorite genre’, which is categorical – and therefore non-scalar data – they choose K-medoids. ...
‘Variance’ represents the degree to which numerical values of a particular variable deviate from its overall mean. You could think of the dispersion of those values plotted on a graph, with the average being at the centre of that graph. The variance provides a measure of how scattered the ...
before it can be used to find the parameters of your model. Your data might need to be converted from string values to a numerical representation. You might have redundant information in your input data. You might need to reduce or expand the dimensions of your input data. Your data might...

A ratio variable, has all the properties of an interval variable, and also has a clear definition of 0.0. When the variable equals 0.0, there is none of that variable. Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight,...
Numerical Example of Bayes' Theorem As a numerical example, imagine there is a drug test that is 98% accurate, meaning that 98% of the time, it shows a true positive result for someone using the drug, and 98% of the time, it shows a true negative result for nonusers of the drug. ...
