void PLearn::StderrStatsIterator::declareOptions (  OptionList &  ol  )  [static, protected]

redefine this in subclasses: call declareOption(...) for each option, and then call inherited::declareOptions(options) ( see the declareOption function further down) ex: static void declareOptions(OptionList& ol) { declareOption(ol, "inputsize", &MyObject::inputsize_, OptionBase::buildoption, "the size of the input\n it must be provided"); declareOption(ol, "weights", &MyObject::weights, OptionBase::learntoption, "the learnt model weights"); inherited::declareOptions(ol); } Reimplemented from PLearn::StatsIterator. Definition at line 310 of file StatsIterator.cc. References PLearn::declareOption(), and PLearn::OptionList.

bool PLearn::StderrStatsIterator::finish (   )  [virtual]

Call this method when all the data has been shown (through update) If the method returns false, then a further pass through the data is required. Implements PLearn::StatsIterator. Definition at line 296 of file StatsIterator.cc. References PLearn::TVec< T >::length(), mean, meansquared, nsamples, PLearn::sqrt(), and PLearn::squareSubtract().

virtual string PLearn::StderrStatsIterator::info (   )  const [inline, virtual]

returns a bit more informative string about object (default returns classname()) Reimplemented from PLearn::Object. Definition at line 194 of file StatsIterator.h.

void PLearn::StderrStatsIterator::init (  int  inputsize  )  [virtual]

Call this method once with the correct inputsize. Implements PLearn::StatsIterator. Definition at line 281 of file StatsIterator.cc. References PLearn::TVec< int >::clear(), mean, meansquared, nsamples, PLearn::TVec< int >::resize(), and PLearn::Vec.

void PLearn::StderrStatsIterator::makeDeepCopyFromShallowCopy (  map< const void *, void * > &  copies  )  [virtual]

Reimplemented from PLearn::StatsIterator. Definition at line 274 of file StatsIterator.cc. References PLearn::deepCopyField(), mean, and meansquared.

void PLearn::StderrStatsIterator::oldread (  istream &  in  )  [virtual]

DEPRECATED For backward compatibility with old saved object. Reimplemented from PLearn::StatsIterator. Definition at line 334 of file StatsIterator.cc. References mean, meansquared, nsamples, PLearn::readField(), PLearn::readFooter(), and PLearn::readHeader().

void PLearn::StderrStatsIterator::oldwrite (  ostream &  out  )  const [virtual]

Reimplemented from PLearn::StatsIterator. Definition at line 324 of file StatsIterator.cc. References mean, meansquared, nsamples, PLearn::writeField(), PLearn::writeFooter(), and PLearn::writeHeader().

PLearn::StderrStatsIterator::PLEARN_DECLARE_OBJECT (  StderrStatsIterator   )

void PLearn::StderrStatsIterator::update (  const Vec &  input  )  [virtual]

Then iterate over the data set and call this method for each row. Implements PLearn::StatsIterator. Definition at line 291 of file StatsIterator.cc. References PLearn::addXandX2IfNonMissing(), mean, meansquared, and nsamples.
