Suppose we want to look at which airlines have similar pricing strategies. The data set looks like this: Variables: Flight Origination, Flight Destination, Airline1 Price, Airline2 Price,…Continue

Hadoop and Data Mining

Hadoop and Big Data are buzzwords these days. How does it affect data mining workers? Should it be completely transparent for people only using analytical tools such as R, SPSS, SAS etc. in their…Continue

Independent variables need to be normally distributed in multiple regression?

Started this discussion. Last reply by Sean Flanigan Jul 20, 2012. 5 Replies

Below is a quote regarding logistic regression. It seems it is saying OLS regression requires independent variables to be normally distributed. Based on my past experience, most independent…Continue

How To Determine If A Sample Is Representative

Started this discussion. Last reply by Varun Bhargava May 24, 2017. 7 Replies

If the sample is obtained through simple random sampling, would it be automatically representative of the population? If not, what is the way to determine if it is representative.Continue

"Or even the mean of sample and population can work I guess"

"Can't we just plot a scatter plot of population and samples and visually confirm that sample selected for training is close to the population. And is it necessary to get rid of the outliers ?"

"More info: What I mean by "price similarly" is when Airline1 prices high on a origination and destination pair, Airline3 and Airline8 also prices high."

The data set looks like this: Variables: Flight Origination, Flight Destination, Airline1 Price, Airline2 Price, ....Airline10 Price. Data:Origination: A, Destination: B, Airline1 Price=100, Airline2 = 120, ...., Airline10=95Origination: A, Destination: C, Airline1 Price=500, Airline2 = 450, ...., Airline10=505...... The expected outcome is like:Airline1, Airline3, Airline8 price similar.Airline2, Airline4 price…See More

"Hi Jason, Hadoop and Big Data on itself does not really help anyone, especially not if it used on a data-management level only. So we could now store even larger data sets and we are able to retrieve them faster than before. Nice, but in principle…"

"Jason, You are completely right in your statement about Hadoop that it is makes data retrieval fater. But it does more than that actually. It has power of distributed computing where you have large number of CPU power to run your…"

"Yes - there is a great deal of demand for data mining/predictive modeling people. Not only that, but there's competition between employers for the best talent & salaries are much better for heavy-duty quant people than they are for entry…"

Lynne Mysliwiec replied to Jason Monte's discussion How To Determine If A Sample Is Representative
"The answer is: No. No sample is guaranteed to be representative of the entire population, although the risk of non-representative samples is reduced as sample size / total N gets larger.  The larger the % of the total population, the lower the…"

Ralph Winters replied to Jason Monte's discussion Hadoop and Data Mining
"I think it will foster different ways of operating on the data, to perform equivalent results.  For example if you are used to doing a regression on a large sample base, you may be forced to perform separate analyses on the various subsets of…"

Hadoop and Data Mining

Hadoop and Big Data are buzzwords these days. How does it affect data mining workers? Should it be completely transparent for people only using analytical tools such as R, SPSS, SAS etc. in their life? I guess Hadoop and Big Data is more at the data-management level. It just makes data retrieval faster and has nothing to do with analytics.See More

Sean Flanigan replied to Jason Monte's discussion Web Analytics vs Data Mining/Predictive Modeling
"The fractional factorial is a higher end breed, more of a GLM traditionally , but there are choice modeling approaches as well (http://www.nobelprize.org/nobel_prizes/economics/laureates/2000/press.html) for these designs. So, the research design…"

Sean Flanigan replied to Jason Monte's discussion Independent variables need to be normally distributed in multiple regression?
"Given dummy codes are not normal, would this generalize to impact the business presentation of "on average a unit increase in x produces an increase in y" if both are not normally distributed, or at least based on some fundamental…"
