R programming, In ks.test(x, y) : p-value will be approximate in the presence of ties
Warning message:In ks.test(x, y) : p-value will be approximate in the presence of tiesThe warning messages are due to the implementation of the KS test in R, which expects a continuous distribution and thus there should not be any identical values in the two datasets i.e. ties.
The presence of ties always generates a warning, since continuous distributions do not generate them. If the ties arose from rounding the tests may be approximately valid, but even modest amounts of rounding can have a significant effect on the calculated statistic.
