fanova.onefactor {fda.usc}

One–way anova model for functional data

Description

One–way anova model for k independent samples of functional data. The function contrasts the null hypothesis of equality of mean functions of functional data based on the an asymptotic version of the anova F–test.

H_0:\, m_1=\ldots=m_k

Usage

fanova.onefactor(
  object,
  group,
  nboot = 100,
  plot = FALSE,
  verbose = FALSE,
  ...
)

Arguments

object

functional response data. fdata class object with n curves.

group

a factor specifying the class for each curve.

nboot

number of bootstrap samples.

plot

if TRUE, plot the mean of each factor level and the results of test.

verbose

if TRUE, print intermediate results.

...

further arguments passed to or from other methods.

Details

The function returns the p–value of test using one–way anova model over nboot runs.

Value

Returns:

• p-value probability of rejecting the null hypothesis H0 at a significance level

• stat statistic value of test.

• wm statistic values of bootstrap resamples.

Note

anova.onefactor deprecated.
