ds.corTest | R Documentation |
This is similar to the R stats function cor.test
.
ds.corTest( x = NULL, y = NULL, method = "pearson", exact = NULL, conf.level = 0.95, type = "split", datasources = NULL )
x |
a character string providing the name of a numerical vector. |
y |
a character string providing the name of a numerical vector. |
method |
a character string indicating which correlation coefficient is to be used for the test. One of "pearson", "kendall", or "spearman", can be abbreviated. Default is set to "pearson". |
exact |
a logical indicating whether an exact p-value should be computed. Used for
Kendall's tau and Spearman's rho. See ‘Details’ of R stats function |
conf.level |
confidence level for the returned confidence interval. Currently only used for the Pearson product moment correlation coefficient if there are at least 4 complete pairs of observations. Default is set to 0.95. |
type |
a character string that represents the type of analysis to carry out.
This must be set to |
datasources |
a list of |
Runs a two-sided correlation test between paired samples, using one of
Pearson's product moment correlation coefficient, Kendall's tau or Spearman's rho.
Server function called: corTestDS
ds.corTest
returns to the client-side the results of the correlation test.
