Summary of an "addt.fit" object.

Provides a brief summary of an addt.fit object.

## S3 method for class 'addt.fit'
summary(object, ...)

`object`	An `addt.fit` object.
`...`	Optional arguments.

Returns a list whose items vary depending on which procedure was used in addt.fit. If proc="ML", then the output has the following items:

`coef.mle.mat`	A matrix giving the estimated coefficients, their standard errors, and the lower and upper bounds of a 95% confidence interval.
`ti.CI`	The estimated thermal index of the material, its standard error, and 95% confidence interval.
`logLik`	The maximum log-likelihood value achieved.

If proc="LS", the output has the following items:

`coefs`	A vector giving the estimated coefficients for the time-temperature line.
`TI`	The estimated thermal index of the material.
`interp.time`	A matrix contains the interpolated time at the failure.threshold specified for each temperature level.

If proc="SemiPara", the output has the following items:

`betahat`	An estimate of our model coefficient under the users chosen setups.
`knots`	Knots used in the B-spline, these are the optimal knots if best.knots=TRUE.
`Loglik`	The maximum log-likelihood value achieved.
`aic`	aic value for the final model.
`aicc`	aicc value for the final model.

If proc="All", the output will give the preceeding values for all the LS.obj, ML.obj and SemiPara.obj.
