Dark adaptation data.
Description
This data was extracted from Figure 1 in Rushton's paradox: rod dark adaptation after flash photolysis, E.N.Pugh Jr. The Journal of Physiology, 1975.
Usage
data("dark")Format
dark is a list of 15 items, that are used or created by the functions in this package.
Details
The items are:
$time: the time of observations
$thrs: the thresholds
$fit: thresholds predicted by the model
$resid: residuals between the fitted model and observed data
$R2: the coefficient of determination
$Bootstrap: a table of quantiles (2.5%, 50% and 97.5%) for the parameter estimates from bootstrap methods
$weight: the parameter estimate divided by the 95% quantile range
$valid: an integer array indicating whether the quantile range encloses zero.
$opt: parameter estimates of the optimal model
$Mod: a string describing the optimal model
$Pn: the number of parameters in the optimal model
$AIC: an array with the AICc scores for the three models
$val: sum of residuals squared
$call: the last function call that produced the object
$data: the source of the data
