I would like to do some research on multi-factor analysis. the factors I compiled mostly come from price, volume, and time relationships such as short term momentum, rsi, macd, etc, plus some fundamental factors. I have two questions for those experienced in multi-factor analysis: 1) is it possible to use for multi-factor analysis for short term market timing? 2) which package to use for this analysis? i do not want to write it up myself, which is too time consuming.
