alt.fit R Documentation
Modify an "alt" Object Establishing a Accelerated Life Relationship Fit
Description
This function generates a linear fit to the median or characteristic life estimates of the provided data sets.
Usage
alt.fit(x, omit_set=0)
Arguments
x
An "alt" object as modified by "alt.parallel".
omit_set
An optional vector listing any data set(s) that judged to be excluded from the accelerated life relationship determination.
Details
A linear model fit is made of the median or characteristic life estimates of applicable data sets weighted by number of failure points per each.
The returned object can be plotted using S3 function "plot.alt" placing the failure points (taking intervals
as mean time points) in accordance with the specified alt.model relationship. The fitted relationship line will be displayed
as well as the default percentile "c(10,90)" lines.
Value
The input object will be returned with the addition of a "$alt_coef" element.
