p.cont: p-value calculator for continous variables

In imbi-heidelberg/DescrTab: Creates a table with descriptive statistics

Description

Calculate the p-value for continous variables. The decision which test to use is equal to m.cont. The p-value is calculated using one of the four tests: Wilcoxon-Test, t-Test, Kruskal-Test, Anova.

Usage

p.cont(
  x,
  group,
  paired = F,
  is.ordered = F,
  nonparametric = F,
  t.log = F,
  var.equal = F,
  index = c(),
  create = "tex"
)

Arguments

x	Vector of the continous variable.
group	Vector of the grouping variable.
paired	Logical. Is the categorial Variable paired?
is.ordered	Logical. Is the categorial Variable ordered?
nonparametric	Logical. Should the continuous variable tested by using non-parametric methods.
t.log	Logical. Should be used the log of the original data.
var.equal	Logical. Should variances be assumed to be equal when applying t-tests?
index	Optional. Label for the footnote. The footnotes aren't produced in this function.
create	Which output document should be produced in the following step (one of "pdf", "tex", "knitr", or "word").

Details

Wilcoxon Test: A nonparametric Test for a comparison of 2 dependent samples. (see wilcox.test). Mann-Whitney-U Test: A nonparametric Test for a comparison of 2 independent samples. ( see wilcox.test). t-Test: A parametric Test for a comparison of 2 (in)dependent samples. (see t.test). Friedman-Test: A nonparametric Test for a comparison of more than 2 dependent samples. (see friedman.test). Anova Type III: A parametric Test for a comparison of more than 2 dependent samples. (see Anova with ). Kruskal-Wallis-Test: A nonparametric Test for a comparison of more than 2 independent samples. (see kruskal.test). Anova: A parametric Test for a comparison of more than 2 independent samples. (see aov).

Value
