'''Normal Distribution General Example All Data Type'''
#REDIRECT[[Normal_Distribution_Examples#Times-to-Failure_with_All_Types_of_Censored_Data]]
 
Suppose our data set includes left and right censored, interval censored and complete data as shown in the following table.
 
'''Solution'''
 
This data set can be entered into Weibull++ by selecting the data type Times to Failure, with Right Censored Data (Suspensions), with Interval and Left Censored Data and with Grouped Observations.
 
The computed parameters using maximum likelihood are:
 
::<math>\begin{align}
  & \widehat{\mu }= & 48.11 \\
& {{{\hat{\sigma }}}_{T}}= & 26.42 
\end{align}</math>
 
For rank regression on x:
 
::<math>\begin{align}
  & \widehat{\mu }= & 49.99 \\
& {{{\hat{\sigma }}}_{T}}= & 30.17 
\end{align}</math>
 
For rank regression on y:
 
::<math>\begin{align}
  & \widehat{\mu }= & 51.61 \\
& {{{\hat{\sigma }}}_{T}}= & 33.07 
\end{align}</math>
