'''Weibull++ Non-Parametric LDA Plot Example'''
#REDIRECT[[Weibull++ Non-Parametric LDA Plot Example]]
 
This example shows how to use Weibull++ to do non-parametric LDA analysis. Weibull++ has three different  non-parametric LDA method: Kaplan-Meier, Actuarial Standard, and Actuarial Simple. They are very similar.
 
Assume we have the following data.

Please analyze the above data using Kaplan-Meier method in Weibull++.
 
'''Solution'''
 
'''Step 1:''' Create a Non-Parametric Specialized Folio.

'''Step 2:''' Enter the data as given in below Figure:

In the control panel, a confidence level can be entered. '''Reliability''' at each '''State End Time''' is calculated and plotted together with the confidence bounds.
 
'''Step 3:''' Plot the result.

Since the analysis is done by non-parametric method, only the reliability at the observed state time can be calculated. Non-parametric methods cannot be used for extrapolation and interpolation.
 
'''Step 4:''' The results also can be viewed by clicking '''Non-Parametric Results''':
