I ve fitted a VECM model in R, and converted in to a VAR representation. I would like to use this model to predict the future value of a response variable based on different scenarios for the ...

I have a data file m.txt that looks something like this (with a lot more points): 286.842995 3.444398 3.707202 338.227797 3.597597 283.740414 3.514729 3.512116 3.744235 3.365461 3.384880 Some of the ...

I haven t really used variance calculation that much, and I don t know quite what to expect. Actually I m not too good with math at all. I have a an array of 1000000 random numeric values in the ...

I m trying to generate GOFrame objects to generate a gene ontology mapping in R for unsupported organisms (see http://www.bioconductor.org/packages/release/bioc/vignettes/GOstats/inst/doc/...

Here is a fun one: I need to generate random x/y pairs that are correlated at a given value of Pearson product moment correlation coefficient, or Pearson r. You can imagine this as two arrays, array ...
