SYNOPSIS
SUBROUTINE NOROUT(X,N)
real(kind=wp),intent(in) :: X(:) integer,intent(in) :: N
DESCRIPTION
NOROUT(3f) performs a normal outlier analysis on the data in the input vector X.
This analysis consists of--
1. various normal outlier statistics; 2. various partial sample means 3. various partial sample standard deviations; 4. the first 40 and last 40 ordered observations; 5. a line plot; and 6. a normal probability plot. When the first 40 and last 40 ordered observations are printed out, also included for each of the 40+40 = 80 listed data values is the corresponding residual about the (full) sample mean, the standardized residual, the normal n(0,1) value for the standardized residual, and the position number in the original data vector X.
This last piece of information allows the data analyst to easily locate back in the original data vector. A suspected outlier or otherwise interesting observation.
INPUT ARGUMENTS
X The vector of (unsorted or sorted) observations. N The integer number of observations in the vector X. The maximum allowable value of N for this subroutine is 7500.
OUTPUT
4 pages of automatic printout as described in the description above.
