selbal.aux: The balance defined in the order its variables were selected

In malucalle/selbal: Finding highly - associated balances with the response variable.

The balance defined in the order its variables were selected

Description

The balance defined in the order its variables were selected

Usage

selbal.aux(x, y, th.imp = 0, covar = NULL, logit.acc = "AUC",
  logt = T, maxV = 1e+10, zero.rep = "bayes")

Arguments

x	a matrix object with the information of variables (columns) for each sample (rows).
y	the response variable, either continuous or dichotomous.
th.imp	the minimum increment needed when adding a new variable into the balance, in order to consider an improvement.
covar	data.frame with the variables to adjust for (columns).
logit.acc	when y is dichotomous, the measure to compute for the correlation between y and the proposed balance adjusting for covariates. One of the following values: "Rsq" (default), "AUC" or "Tjur".
logt	a logical value indicating if the data needs to be log-transformed.
maxV	the number maximum of variables defining the balance.

Value

A data.frame with the following objects:

• Taxa the name of the taxa added into the balance.

• Group NUM if the variable is added into the numerator and DEN if it is added in the denominator.

Examples

# Load data set
  load("HIV.rda")
# Define x and y
  x <- HIV[,1:60]
  y <- HIV[,62]
# Run the algorithm
  Bal <- selbal.aux(x,y)
