Subject: PREDICITON OF PARAMETER
I have some laboratory data (accelerated test)for Grade 1 item and Grade 2 item, i have estimated parameters of weibull distribution. For the Grade 1 item i have field data and i have estimated the parameters of weibull distribution.
Here i have a problem in correlating the field data with laboratory data for grade 1 item. How can i correlate this Grade 1 data?
By using this same same logic How can one predict the field data parameters for Grade 2 ?
Please help me in this case....
