Description Usage Arguments Value References Examples
This function implements a wide assortment of options for linear regression fitting of distributions specific to reliability analysis for the Abernethy Reliability Methods project.
1 |
x |
A dataframe such as generated by getPPP with column names 'data' and 'ppp'. |
dist |
A string defining a distribution to be fit. Implemented distributions are "weibull" (default), "lnorm", and "gumbel" (Extreme Value Type 1) |
npar |
Number of parameters to evaluate. This really is only looking for potential value of 3 for 3rd parameter optimization. Any other value will resolve the same as default of 2. |
reg_method |
A string defining a method of regression optimization whether "XonY" axis(default and "best practice for standard small sample fitting) or "YonX" axis for alternative study ("YonX" recommended for an inspection option by Abernethy). |
Returns a named vector with parameters of the distribution fit and goodness of fit in terms of R squared.
