estimateDimension

A prismaData object loaded via loadPrismaData

prismaData

Error probability for confidence intervals

alpha

The number of scrambled samples that should be used to estimate the
    noise model. NULL means to use the complete data set.

nScrambleSamples

Matrix factorization methods compress the original data matrix $A \in
  R^{f,N}$ with $f$ features and $N$ samples into two parts,
  namely $A = B C$ with $B \in R^{f,k}, C\in R^{k,
    N}$. The function estimateDimension estimates $k$ based on a noise
  model estimated from a scrambled version of the original data matrix.

The PRISMA package is capable of loading and processing huge text
    corpora processed with the sally toolbox (http://www.mlsec.org/sally/).
    sally acts as a very fast preprocessor which splits the text files into
    tokens or n-grams. These output files can then be read with the PRISMA
    package which applies testing-based token selection and has some
    replicate-aware, highly tuned non-negative matrix factorization and
    principal component analysis implementation which allows the processing of
    very big data sets even on desktop machines.
