Correlation and linear regression analysis mini project

They can be used for non-linear regression, time-series modelling, classification, and many other problems. Differentially private database release via kernel mean embeddings. We lay theoretical foundations for new database release mechanisms that allow third-parties to construct consistent estimators of population statistics, while ensuring that the privacy of each individual contributing to the database is protected.

I am not a pharmacologist. I am not a researcher. I am not a statistician. This is not medical advice. This is really weird and you should not take it too seriously until it has been confirmed] I.

Our linear regression project focuses on the correlation between the two main variables, the age of the respondent and also the religious observance (in hours) the respondent spends per week. We wanted to see if there was any correlation what so ever in age and religious observance while attending college. International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research. So, how can we interpret the Pearson correlation? Turns out, there is a clear connection between Pearson correlation and the slope of a line. In the above figure, a regression line through each scatter plot is shown. The regression line is optimal, as it minimizes the distance of all points to itself.

Are these any good? I looked at four of the largest such databases — Drugs. Then I correlated them with one another to see if the five sites mostly agreed. Correlations between CrazyMeds and DrugLib were generally small or negative. So I threw out the two offending sites and kept Drugs.

I normalized all the data, then took the weighted average of all three sites. Everyone secretly knows Nardil and Parnate the two commonly-used drugs in the MAOI class are excellent antidepressants1. Likewise, I feel pretty good to see that Serzone, which I recently defended, is number five.

The table also matches the evidence from chemistry — drugs with similar molecular structure get similar ratings, as do drugs with similar function. This is, I think, a good list. Which is too bad, because it makes the next part that much more terrifying. There is a sixth major Internet database of drug ratings.

It is called RateRxand it differs from the other five in an important way: RateRx has a modest but respectable sample size — the drugs on my list got between 32 and 70 doctor reviews. So patients pretty much agree on which drugs are good and which are bad?

Doctor reviews on RateRx correlated at The negative relationship is nonsignificant, but that just means that at best, doctor reviews are totally uncorrelated with patient consensus. This has an obvious but very disturbing corollary. But total number of online reviews makes a pretty good proxy.

After all, the more patients are using a drug, the more are likely to review it.

Cymbalta was also the best selling antidepressant of So number of reviews seems to be a decent correlate for amount a drug is used. But amount the drug gets used correlates negatively with patient rating of the drug So the more patients like a drug, the less likely it is to be prescribed2.

Anyone familiar with these medications reading the table above has probably already noticed this one, but I figured I might as well make it official. I correlated the average rating of each drug with the year it came on the market.

The correlation was So, how can we interpret the Pearson correlation? Turns out, there is a clear connection between Pearson correlation and the slope of a line. In the above figure, a regression line through each scatter plot is shown. The regression line is optimal, as it minimizes the distance of all points to itself.

Every twenty years, pharmaceutical companies have an incentive to suddenly declare that all their old antidepressants were awful and you should never use them, but whatever new antidepressant they managed to dredge up is super awesome and you should use it all the time.
