Is regression a good method for prediction when a variable is dependent on multiple attributes each having seasonal variations

 

For simple or multiple regression, you can’t directly conduct regression method for your data, since one of the assumption for simple/multiple regression is independent variable should not have multicolinearity among them. Maybe you can use robust regrssion or use time series method (ARIMA) that can address your data.

 

It is quite common to perform seasonal adjustment of data where there is a strong seasonal trend, then use the seasonally-adjusted data in further analyses. Many textbooks and websites describe techniques for doing such adjustments. With daily numbers you must take into account both day of the week AND season, and this can get a little tricky. For example December 2011 was odd because by the last pre-Christmas Saturday, which is usually a big shopping day, many of us had already finished buying gifts since Christmas fell on a Sunday. Anyway, look up how to do such adjustments, and you can use the adjusted data as the inputs for linear regression.

 

But in my data there is no collinearity and whereever it exists i can reduce those attributes during dimensionality reduction process

Hi i there My name is Bryan Downing. I am part of a company called QuantLabs.Net This is specifically a company with a high profile blog about technology, trading, financial, investment, quant, etc. It posts things on how to do job interviews with large companies like Morgan Stanley, Bloomberg, Citibank, and IBM. It also posts different unique tips and tricks on Java, C++, or C programming. It posts about different techniques in learning about Matlab and building models or strategies. There is a lot here if you are into venturing into the financial world like quant or technical analysis. It also discusses the future generation of trading and programming Specialties: C++, Java, C#, Matlab, quant, models, strategies, technical analysis, linux, windows P.S. I have been known to be the worst typist. Do not be offended by it as I like to bang stuff out and put priorty of what I do over typing. Maybe one day I can get a full time copy editor to help out. Do note I prefer videos as they are much easier to produce so check out my many video at youtube.com/quantlabs
