Experts working in
mathematical statistics and finance,
who actively publish results in the field and
aim at bridging the gap
between theory and practice
by implementing a complete environment
for the inference and simulation
of Stochastic Differential Equations
What is a yuima object?
What can you do with
a yuima object?
R example…
yuima <- setYuima(
data = setData(FB$FB.Close, delta = 1/252),
model = setModel(drift="mu*x", diffusion="sigma*x"))
R example…
yuima <- setYuima(
data = setData(FB$FB.Close, delta = 1/252),
model = setModel(drift="mu*x", diffusion="sigma*x"))
qmle(yuima, start = list(mu = 0, sigma = 0.1))
Quasi-Maximum likelihood estimation
qmle(yuima = yuima, start = list(mu = 0, sigma = 0.1))
Coefficients:

R example…
yuima <- setYuima(
data = setData(FB$FB.Close, delta = 1/252),
model = setModel(drift="mu*x", diffusion="sigma*x"))
qmle(yuima, start = list(mu = 0, sigma = 0.1))
simulate(yuima@model,
true.parameter = list(mu = 0.35, sigma = 0.3895313),
sampling = setSampling(delta = 1/252, n = 252),
xinit = last(FB$FB.Close))
yuima breakthrough
do things much more easily than before
do things much faster than before
do things you couldn’t do before
yuimaGUI
not just an interface
Running yuima function from a Graphical User
Interface
Improving User experience and getting straight to the
point
yuimaGUI
still lacks some features
but …
Thank you for your
help (and amazing
package)!

INSIGHT
Yuima Koji
(Vimalakirti Nirdesa)
Yuima’s teaching is
about seeing through
the trappings of
theoretical issues to
the spiritual heart of
the wonder of reality
