MRBPObj-class: Class '"MRBPObj"'

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

Description

The MRBPObj class holds model specification and output from the Multiresponse Randomized Block procedure. The summary.MRBPObj class represents the summary of these objects.

Objects from the Class

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

Slots

inputData:

The data.frame used in the analysis.

DistExp:

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

NumVars:

The number of variables specified in the function call.

NumBlocks:

The number of blocks in the blocking variable.

NumGrps:

The number of groups in the grouping variable.

NumPerm:

The number of permutations used in the analysis if specified in the function call.

NumObs:

The total number of observations in the data.frame.

AlignVals:

The block alignment values (if align=TRUE)

Align:

A logical indicating whether the data has been aligned so that the median of all blocks is equal.

Exact:

A logical indicating whether an exact test was performed.

Resample:

A logical indicating whether resampling is performed.

Commensurate:

A logical indicating whether the data were commensurated.

ObsDelta:

Delta Observed.

ExpectDelta:

The expected value of Delta (only calculated for the Pearson type III moments approximation).

DeltaVar:

The variance of Delta (only calculated for the Pearson type III moments approximation).

DeltaSkew:

The skew of Delta (only calculated for the Pearson type III moments approximation).

AgreeVal:

The agreement measure among blocks.

StdStat:

The standardized test statistic.

P_value:

The probability of a smaller or equal delta.

Call:

The original function call.

CommenAvgDist:

If commensuration was done these are the commensurate average distances.

SaveTest:

A logical indicating whether to save resample values of Delta.

PermVals:

If save.test=TRUE this holds the resample values of Delta.

group.names:

The names of the groups used in the analysis.

Methods
