Question
Code from statistical toolbox
Hi,
I have problems with using the statistical toolbox on some code so need to replace all code which calls functions and so on from the toolbox. I still need the functionality so appropriate code needs to be replaced with working (free) replacements. I'm running short of time as well :(
Any suggestions?
James

Well, first you will get 'Undefined function or variable' error whilw running your code.
If you are interested in a particular function you can run
which function_name
to see where this function located. If it's somewhere under /toolbox/stats, it belongs to the Statistical Toolbox.
You can also run DEPFUN and DEPDIR functions to find all functions/directories your code depends on. See help for more details. For a large complex code it may take a lot of time and produce a lot of output, so you will have to parse it.
Hi again,
So I have made some headway, although am stuck on
normcdf(-40,mu,sigma)
statset('MaxIter',10000, 'MaxFunEvals',10000, 'Robust','on', ...
'TolBnd',1000, 'TolFun',1000)
mle(values, 'pdf',pdf_truncnorm, 'start',start, ...
'lower',[-Inf 0], 'options',options)
Any suggestions on replacements?
Cheers,
James
For normcdf try this:
http://www.mathworks.com/m
Your statset command just creates the same structure as the following code:
options = struct(...
'Display', [], 'MaxFunEvals', 10000, 'MaxIter', 10000, ...
'TolBnd', 1000, 'TolFun', 1000, 'TolTypeFun', [], ...
'TolX', [],'TolTypeX', [],'GradObj', [], 'Jacobian', [], ...
'DerivStep', [], 'FunValCheck', [], 'Robust', 'on', ...
'WgtFun', 'bisquare', 'Tune', 4.6850, 'UseParallel', [], ...
'UseSubstreams', [], 'Streams', [], 'OutputFcn', []);
As for MLE, I cannot give you a simple replacement. Look at the MatlabCentral FileExchange (http://www.mathworks.com/

What functions are you talking about? Some functions from Statistical Toolbox are not so difficult to implement. For many you can find replacement on MatlabCental's File Exchange: http://www.mathworks.com/m
Cannot help you without more details.
