Weibull Analysis: Results (Grouped Data) - Reliability Tab

Select the Reliability tab of the Weibull Analysis: Results (Grouped Data) dialog box to access options to plot (or display) the reliability function for the current parameter values/estimates - see Estimate tab (e.g., the weighted least squares estimates, if you accepted the default parameter values). Note that the quantities plotted or displayed via these options are derived from the life table (see also the Survival Analysis module or Weibull CDF, reliability, and hazard functions for additional details).

Time-to-fail. vs. R(t).
R(t). Click this button to produce a plot of the reliability function (complement of the cumulative distribution function; see the Introductory Overview) computed from the current parameter values/estimates (see Estimate tab).
Probability plot
Click this button to produce a Weibull probability plot. This plot will show on the left y-axis the quantity log(log(1/(1-F(t)))), where F(t) denotes the life table estimate of the cumulative distribution function; the x-axis will show the quantity log(lower interval boundaries minus location parameter). As described in the Introductory Overview, this plot can also be used to derive parameter estimates, and those estimates are displayed in the title of the probability plot (along with the current parameter values/estimates (see Estimate tab).
Reliability
Click this button to produce a spreadsheet with the reliability and cumulative distribution function values. Both the life table estimates as well as the estimated (expected) values for the Weibull distribution, based on the current parameter values/estimates (see Estimate tab) are computed (see also Weibull CDF, reliability, and hazard functions).
Life table
Click this button to produce a life table for the current grouped input data. For a detailed description of the quantities listed in this table, refer to the respective description in the Survival Analysis module.
