how many variables in a dataset how close is a sample to its dataset how many variables are there in the same dataset how does dataset compare how much does a data set contain why are some variables compared how many variables in a dataset what is the data set that has about 400 variables and does the graph varying too much is it correlated when you are comparing different variables in graph how is the data correlated why is the pca not too accurate why don't some variables in a dataset have too much variance why is data not correlated how many variables are in a large data set do a dataset have too much correlated variables how many variables in a dataset ppca is dataset too large for different variables are the different variables in a dataset more similar how many variables in the graph do the variables of the dataset converge?
