|
readevent |
readevent reads a key- or a mouse- event while a program is running.
An "event" is a stroke of a key or a click of a mouse button.
readevent will be mainly useful for letting XploRe know whether
such an event has occured and to get some special information like
the coordinates where the mouse click happened or a key code.
readevent will "record" the relevant event if it ocurred previous to
the moment when readevent is called. readevent can therefore be used
to "tell" the program that the event has happened. Sometimes it is
usefull to call at first setmode(...., 2) to disable default event
handling.

the estimator is evaluated for all the combinations of q and m.

in the third column the value of q.

Calculation of the rescaled variance test for I(0) against long-memory

deviation from the mean. The limit distribution of this statistic is a Brownian
bridge whose distribution is related to the distribution of the Kolmogorov
statistic. This statistic can also be used for detecting long-memory in ARCH
models.
The first argument of the quantlet is the series, the second optional argument
is the vector of truncation lags for the spectral based autocorrelation
consistent estimator of the variance. If this optional argument is not
provided, the default vector of truncation lags used by Kwiatkowski, Phillips,
Schmidt and Shin is used. The quantlet returns the order of the truncation lag,
the rescaled variance statistic, with the 95% critical value.
