Dark (version 0.9.4)

dark: 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 14 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
