Description Usage Arguments Value Examples
Finds the cross-validation bandwidth for the local polynomial estimator of the psychometric function (PF) with guessing and lapsing rates specified in lims.
1 | bandwidth_cross_validation( r, m, x, H, link = c( "logit" ), guessing = 0, lapsing = 0, K = 2, p = 1, ker = c( "dnorm" ), maxiter = 50, tol = 1e-6, method = c( "all" ) )
|
r |
number of successes in points |
m |
number of trials in points |
x |
stimulus levels |
H |
minimum and maximum values of bandwidth to be considered |
link |
name of the link function to be used; default is "logit" |
guessing |
guessing rate; default is 0 |
lapsing |
lapsing rate; default is 0 |
K |
power parameter for Weibull and reverse Weibull link; default is 2 |
p |
order of the polynomial; default is 1 |
ker |
kernel function for weights; default "dnorm" |
maxiter |
maximum number of iterations in Fisher scoring; default is 50 |
tol |
tolerance level at which to stop Fisher scoring; default is 1e-6 |
method |
loss function to be used in cross-validation: choose from: 'ISEeta', 'ISE', 'deviance'; default is "all" |
h |
cross-validation bandwidth for the chosen method; if no method was specified, then it a list of three elements with entries corresponding to the estimated bandwidths on p-scale ( |
