MRSPObj-class: Class '"MRSPObj"'

In Blossom: Statistical Comparisons with Distance-Function Based Permutation Tests

Description

The MRSPObj class holds model specification and output from the Multiresponse sequence procedure. The summary.MRSPObj class represents the summary of these objects.

Objects from the Class

Objects can be created by calls of the form new("MRSPObj", ...) or, more commonly, via the sp function.

Slots

NumObs:

The total number of observations in the original data set.

NumVars:

The number of response variables used in the multiresponse sequence procedure.

DistExp:

The distance exponent used in calculation of distances between pairs of observations.

NumPerm:

The number of permutations use if a permutation test was performed.

DoResamp:

A logical value indicating whether a resample test was performed.

Exact:

A logical value indicating whether an exact test was performed.

Commens:

A logical value indicating whether the data were commensurated.

inputData:

The original data.frame or matrix containing the response variables for which the test was run.

TestStat:

The standardized test statistic.

ObsDelta:

The observed delta value based on distances between sequentially ordered locations.

ExpectDelta:

The average distance among locations ignoring serial dependence.

DeltaVar:

Delta variance.

DeltaSkew:

Delta Skewness.

RhoAgreement:

The agreement measure or percent reduction in average distance between sequentially ordered values (observed delta) over that expected without any order (expected delta).

P_value:

The p-value for the test.

Call:

The original function call.

SaveTest:

A logical indicating whether to return Monte Carlo resampled test statistic values.

PermVals:

If save.test was specified this vector will hold resampled test statistic values.

CommAvgDist:

If Commensurate was specified this vector contains commensurated values.

signature(x = "MRSPObj"): Extracts the Monte Carlo resampled test statistic values.

show

signature(object = "MRSPObj"): Same as print.

summary
