Determining the Basic Variables for Diagnosis of Patients With Thyroid Gland By Using S/N Ratio Methods.

Abstract

There are many situations in which the simultaneous monitoring or control of two or
 more related quality characteristics is necessary. Multivariate analysis utilize the
 additional information due to the relationships among the variables and these concepts
 may be used to develop more efficient control charts than the simultaneous operation of
 several university control charts. The most popular multivariate statistical process
 control SPC are the Hotelling's T2
 
 chart. In this paper the S/N ratio is analyzed and
 response effect level are calculated with optimizing the response effect level And to
 explain which of variable is important and necessary to test the chemical analysis in
 Thyroid gland.
