calib.fit-class: General Standard Curve Fitting

In calibFit: Statistical models and tools for assay calibration

Description

calib.fit utilizes two main model types, linear and logistic regression for the purpose of standard curve fitting. It also incorporates several alternatives within each model type to allow for more flexible and reliable fitting.

Slots

coefficients:

Estimates of the coefficients

se.coefficients:

Estimates of the standard errors for the coefficients

sigma:

Standard deviation of model

cov.unscaled:

Unscaled variance-covariance matrix of the coefficients

pom:

Whether or not POM model was used, TRUE or FALSE.

theta:

The estimated value of POM parameter theta

df.residual:

The residual degree of freedom

fitted.values:

The estimated fitted values

residuals:

The values of the residuals

method:

Which algorithm was used to do the optimization (i.e. ML, RML, EM, etc.)

kused:

The number of iteration to convergence of the GLS fit

status:

Indicated whether the algorithm converged

x:

The x values

y:

The y values

logParm:

Indicated whether a log parameterization of the model used

m:

The number of repeated measures used in the model

cv:

Coefficient of variation used

mdc:

Minimum detectable concentration

rdl:

Reliable detection limit

loq:

Limit of quantitation

gradient:

The gradient matrix based off of the final parameter estimates

lof.test:

An slot returing information from a lack of fit (LOF) test.

var.model:

The type of variance model used

conf.level:

Confidence level used

type:

Whether, fpl, tpl, thpl, lin or quad was used.

rdlwarn:

The general model type used, fpl, thpl or lin
