Compute minimum and maximum possible values of z given rounded mu and sigma

Compute minimum and maximum possible values of z given rounded mu and sigma

# S3 method for max.z
min(
  mu,
  sigma,
  mu.dec = pmax(num.deci(mu), num.deci(sigma)),
  sigma.dec = mu.dec
)

Arguments

mu	Vector of reported estimated coefficients
sigma	Vector of reported standard errors
mu.dec	Number of reported decimal digits for mu. By default the maximum of the
long	if TRUE (default return results in a long format)
