Description

Calculates starting values for the vector of (mean1, mean2, var1, corr, var2) from completely observed data.

Usage

1
sv(data, lower1, upper1, lower2, upper2)

Arguments

data

a data frame name.

lower1

the lower bound of the first variable of the two variables whose correlation coefficient to be calculated.

upper1

the upper bound of the first variable of the two variables whose correlation coefficient to be calculated.

lower2

the lower bound of the second variable of the two variables whose correlation coefficient to be calculated.

upper2

the upper bound of the second variable of the two variables whose correlation coefficient to be calculated.

Details

function sv calculates starting values for the vector of (mean1, mean2, var1, corr, var2) from completely observed data.

Value

mu1

starting value for the mean parameter of the first variable.

mu2

starting value for the mean parameter of the second variable.

var1

starting value for the variance parameter of the first variable.

cor

starting value for the correlation coefficient.

var2

starting value for the variance parameter of the second variable.
