Pearson r correlation:Pearson r correlation is widely used in statistics to measure the degree of the relationship between linear related variables. For example, in the stock market, if we want to measure how two commodities are related to each other, Pearsonrcorrelation is used to measure the ...
1.A relationship or connection between two things based on co-occurrence or pattern of change:a correlation between drug abuse and crime. 2.StatisticsThe tendency for two values or variables to change together, in either the same or opposite way:As cigarette smoking increases, so does the incid...
Used to select a variable of interest. Alternative to the argument vars. vars optional character vector containing variable names for correlation analysis. Ignored when dot vars are specified. If vars is NULL, multiple pairwise correlation tests is performed between all variables in the data. If ...

A correlation could be presented in different ways: Positive Correlation: both variables change in the same direction. Neutral Correlation: No relationship in the change of the variables. Negative Correlation: variables change in opposite directions. The performance of some algorithms can deteriorat...
