resampled_ttest: Compute correlated t-statistic and p-value for resampled data

Description

Compute correlated t-statistic and p-value for resampled data

Usage

resampled_ttest(x, y, n, n1, n2, tailed = c("two", "one"), greater = NULL)

Value

data.frame containing the test statistic and p-value

Arguments

x

numeric vector of values for model A

y

numeric vector of values for model B

n

integer denoting number of repeat samples. Defaults to length(x)

n1

integer denoting train set size

n2

integer denoting test set size

tailed

character denoting whether to perform a two-tailed or one-tailed test. Can be one of "two" or "one". Defaults to "two"

greater

character specifying whether "x" or "y" is greater for the one-tailed test if tailed = "one". Defaults to NULL
