The correlation test is based on two factors: the number of observations and the correlation coefficient. The more observations and the stronger the correlation between 2 variables, the more likely it is to reject the null hypothesis of no correlation between these 2 variables. In the...

X must have as many columns as the total number of columns in all of the variables in A, and as many rows as A has observations. B = replacedata(A,X,vars) creates a dataset array B with the same variables as the dataset array A, but with the data for the variables specified in ...

A grouping variable must have the same number of observations (rows) as the table, dataset array, or numeric array you are grouping. Observations that have the same grouping variable value belong to the same group. For example, the following variables comprise the same groups. Each grouping var...
