Description Usage Arguments Value See Also Examples

Performs Two Sample Kolmogorov-Smirnov Tests on a given dataset. The data can be a mixture of numric and factor variables. The results are outputed as a data frame. Furthermore the results an be saved as .csv file to a specified directory. The null hypothesis to the test is that the distributions are equal. Ho: dist(xi) = dist(xj), where i != j.

  directory = NULL)

`dataset`	A dataset on which Kolmogorov-Smirnov Tests are performed.
`y_index`	An integer value, the column index of the response variable, the default is NULL.
`y_name`	A character value, the column name of the response variable, the default is NULL.
`test_dist`	An optional vector to be tested against the variables of the given dataset
`alternative`	The type of hypothesis being tested; two.sided, greater, less. The default is "two.sided"
`file_name`	A character object indicating the file name when saving the data frame. The default is NULL. The name must include the .csv suffixs.
`directory`	A character object specifying the directory where the data frame is to be saved as a .csv file. The default is NULL.

Outputs the Variance F-Tests information as a data frame.

#-- Example Lung Cap Data --#

# Perform Kolmogorov-Smirnov Tests on the entire dataset
tests_ks(dataset = lungcap)

# Perform KS tests specifically in relation to the 2nd column
tests_ks(dataset = lungcap, y_index = 2)

# Perform KS tests specifically in relation to the 'Age' column
tests_ks(dataset = lungcap, y_name = "Age")
