If the correlation between two variables is very high, it implies A. a cause-and-effe
FOODA new method is applied in the determination of correlation coefficient between two variables each containing random error. Using data on properties of scallop meat, the correlation coefficients estimated using the new method differed as much as 11% from those estimated using the conventional ...

The R function cor() can be used to compute the correlation coefficient between two variables, x and y. A simplified format of the function is : # x and y are numeric vectors cor(x, y, method = c("pearson", "kendall", "spearman")) - The pearson correlation method computes a parame...
Use the functioncor.test(x,y) to analyze the correlation coefficient between two variables and to get significance level of the correlation. Three possible correlation methods using the functioncor.test(x,y): pearson, kendall, spearman Infos ...
