- enable fixing the guessing rate to an arbitrary value (? which?) <- This is actually possible by putting a strong prior on the guessing rate...
- what is going on with type checking in psigniplot.GoodnessOfFit?
- add a dictionary to the data objects to make them know what they are (stimulus intensity, ...)
- ROC curves for 1AFC
- Blob size reduction for PF
- Deviance Bootstrap only one sided test
- Error bars on PF. Simply streched bars? (Not sure what is meant)
- 68 Confidence Interval
- In 3d/4d, we could also integrate the posterior without monte carlo methods. Advantage: We get a somehow analytical formula for the posterior. Disadvantage: Might still take quite long and complicates things like CI estimation. In addition, it would be difficult to estimate the errors originating from the fact that we approximate R by a compact interval.
- Plot MCMC diagnostics for all parameters (Not sure what is meant)
- Plot the blue line on top of all the white ones, in the diagnostic plot.
- Alternative view: Shaded region of the posterior instead of 20 sample PFs
- In diagnostic plots, evtl. ad a message on top (what does this mean)
- Replace “model correction” with psi(x) or psi(stimulus intensity) (for people with less elaborated statistics background)
- Influence for Slope and Influence for Threshold seperately instead of using an aggregation in the Plot for the Influential Observers.
- directly use swignifit

- speed!

- noninformative Jeffreys Priors
- seed the random number generator
- Goodness of fit
- Unit test with gamma as a free parameter ( works in principle, but only very rough correspondence to psignifit – should be stricter)
- Bugs with different cores -> no convergence, exceptionally high deviance with ok looking fit, ... This is only due to the logCore-Kernel that returns -inf for contrasts of 0
- codes in sigmoids should be constants with ‘ const unsigned int $VARIBALE’
- add ‘void’ to the clone method calls
- In PsiMCList, getdeviance and setdeviance should be getDeviance and setDeviance
- Review the documentation for BootstrapList
- in PsiSigmoid getcode() should be getCode()
- Use pure virtual functions in PsiSigmoid, PsiCore, and PsiPrior, instead of NotImplemetedError
- Make proper copy constructors for rng.h instead of relying on implicit ones
- When using [] to access elements from the vector class, we need to manually check that the index value is within range. Alternatively we could use the ‘at()’ method, which is index safe, and throws an ‘std::out_of_range’ exception. Consider replacing parts of the code that do th manual checking with calls to ‘at()’. In this case we would also benefit from the swig exception handling for all STL exceptions.

MayBe: - implement fullmodel, nullmodel - Implement alternative SimplexAlgorithm (Numerical Recipes?, gsl-Wrapper-Object?) The current one depends heavily on the initial simplex!

- Perform some gradient based steps after simplex optimization (doesn’t work good)
- alternative: Perform some gradient based steps as a special case of simplex optimization (e.g. particularly good points are moved in the direction of the gradient?)

- add a delete/uninstall possibility
- Makefile/setup.py call for doctests
- List _all_ dependencies in terms of packages for debian (python/numpy headers sphinx etc...)
- Figure for sigmoid/core philosophy

- continue R interface – maybe swig?
- Diagnostic plots: Influential, Parameter inspection
- MCMC convergence diagnostics and Raftery & Lewis stuff

GoodnessOfFit looks better now
