corDS {dsBase} | R Documentation |
This function computes the sum of each vector of variable and the sum of the products of each two variables (i.e. the scalar product of each two vectors).
corDS(x = NULL, y = NULL)
x |
a character, the name of a vector, matrix or dataframe of variables(s) for which the correlation(s) is (are) going to calculated for. |
y |
NULL (default) or the name of a vector, matrix or dataframe with compatible dimensions to x. |
computes the sum of each vector of variable and the sum of the products of each two variables
a list that includes a matrix with elements the sum of products between each two variables, a matrix with elements the sum of the values of each variable, a matrix with elements the number of complete cases in each pair of variables, a list with the number of missing values in each variable separately (columnwise) and the number of missing values casewise, and a vector with elements the sum of squares of each variable. The first disclosure control checks that the number of variables is not bigger than a percentage of the individual-level records (the allowed percentage is pre-specified by the 'nfilter.glm'). The second disclosure control checks that none of them is dichotomous with a level having fewer counts than the pre-specified 'nfilter.tab' threshold.
