Description

This function allows us to compare the treatments averages or the adding of their ranges with the minimal significant difference which can vary from one comparison to another one. This function is used by the HSD, LSD, Kruskal-Wallis, Friedman or Durbin procedures.

Usage

order.group(trt, means, N, MSerror, Tprob, std.err, parameter=1)

Arguments

trt
Treatments
means
Means of treatment
N
Replications
MSerror
Mean square error
Tprob
minimum value for the comparison
std.err
standard error
parameter
Constante 1 (Sd), 0.5 (Sx)

Value

  • trtFactor
  • meansNumeric
  • NNumeric
  • MSerrorNumeric
  • Tprobvalue between 0 and 1
  • std.errNumeric
  • parameterConstant
