I'm interviewing with one very soon. And i love Excel. This is very interesting stuff and gives me so much insight, confidence, and further learning focus to develop my skills and career!
This is incredible and I don't know why we didn't learn this in school (or even in grad school) but all the better to learn from you Dave! Thank you for sharing your knowledge!
I love how you solve this type of analysis with Excel cause you can see everything step-by-step. I read and followed an article to do it with R but I didn't know what was happening behind the algorithm and was pretty difficult to understand till now. Thanks Dave!
Thank you for the explanation! I’m planning on using python for my mba, but seeing you explain it using excel really helped me understand the concept in high level way
Awesome stuff David. I’ve used countifs in excel to associate two different criterias. One main criteria with a table of others. Then I create another column of total frequencies with a final hit percentage. I used a data link to change the main criteria. Using solver I could dig even deeper. Maybe I’ll look at R to get a full count down from best to second best, etc.
Thanks for a great video! I actually tried your model to analyze some data from my own company, and set it up with 4-ways lift and 5-ways lift. When trying the 5-ways lift I encountered a problem with the Solver, it actually picked the same decision variable twice. In the Titanic Dataset this could for example be "Female", "Firstclass", "Istriplet", "Female" and "Survived" - that is "female" is choocen twice. Do you happen to know how we can make a constraint that ensure unique decision variables? Thanks in advance for any help.
Hey David, Great video! I wanted to point out that you don't mention that the formula for the occurrences needs to be entered as an array and it doesn't show that in the video either. Took me a long time to figure this out and get the formulas to work correctly :/
TBH I was a little skeptical to start a 20 min video on this but this was a very efficient way of explaining each and everything. I am really thankful to TH-cam algorithm that I it showed on the top of my list. LIKED, SUBSCRIBED (for all notifications). also hyped to learn R with @david. Thanks Man! Happy new year!
David, excellent video, so logical and clear, as with your other videos. I see that you base it on binary values of 0 or 1 but what if the characterstics have multiple values such as a likert based scale or for example such as a person's age?
Hi David, I am wondering if I can use this technique to segment the market for my thesis. In my survey, I have a lot of categorical variables such as the living area, income (in classes), education, etc. The purpose of my thesis is to research if there is a link between these categorical variables and the interest in the product that my thesis company is selling. Do you recommend using the market basket analysis for this or are there any other data analysis methods that will be suitable for this topic? Ps: Thanks for your very informative videos, I genuinely think your work will help me loads with my thesis.
Thank you for the feedback, much appreciated! Could you provide some more context on this? Are you referring to video context focused on the techniques/algorithms in the abstract? For example, in this video I don't cover the apriori algorithm that is a common market basket analysis implementation.
@@DaveOnData sure! I was trying to say that the videos that I enjoy the most are the ones that you provide a bit of context on a particular technique/algorithm e do a quick showcase in it`s application. Another example was the "Classification Tree Intuition" video. I really liked this Market Basket Analysis video in particular, because your formalized for me a type of analysis that I've done before, but wasn't even aware that it had a name. So it was particularly useful for me, to have a more formal grasp of the technique and be able to google further into it! Of course, it is just my opinion. I'll keep a look out for your future content either way! Keep it up! 🖤
Awesome, thanks for the clarification! I'm thinking you might like my latest video on K-means cluster analysis with Excel: th-cam.com/video/YuxwkchSAW4/w-d-xo.html
Outstanding tutorial! You present very well and your method of teaching is excellent. I have used Python for amateur data analysis but I have not used R. Do you see a big difference between the two? Keep in mind I'm not a mathematician or computer science guy. 👍👍
Thanks, Ajay! Glad you liked the video. In a nutshell: Support - The percentage of transactions in the data with a particular itemset. For example, using the Titanic data, the percentage of passengers that were both female and traveling in 1st class. Confidence - The probability that a transaction has the items on the left-hand side of the rule and also contains the item on the right-hand side of the rule. Take the following rule using the Titanic data: {female, 1st Class} => Survived The confidence is the probability of seeing females traveling in first class that survived.
Hi David, I'm looking at my transactional data where each row represents an order and the columns are the products (107 total columns). For each order (row), I have either a 1 (purchased) or 0 (did not purchase) in every cell. I went through your tutorial and it was great. But what I do not understand is that I do not have a RH column. If your example, you had RH as survived 1 or 0. But I do not have such a column as every row is a purchase so yes, every one purchased something. What am I to do?
Hi David, great tutorial. Q: how can you use the same concept for associations that are in decimals like 0.8, 0.4, 0, 1? and how can you highlight that significance is above 0.7 for instance? is that doable in excel?
This video is great but does anyone know how to organize raw data into a workable table? What do you do to organize the data if you have columns with variables in random order. Using the titanic example, what if your passenger data looks like this for thousands of rows: Passenger 1| single | survived | third class | adult Passenger 2| survived | child | with group | second class
I Finally mangaed to duplicate this in Power BI. Nearly broke me but I feel like I've got superpowers now :) The formula for 3 way lift however is different from the traditional formula seen elsewhere (Number of A,B, C Occurences / (Total transactions * Fraction of A occurrences * Fraction of B occurrences * Fraction of C occurrences)). This Formula used here seems to be (Number of A,B, C Occurences / (Fraction of A Occurances * Fraction of B&C Occurances). Is there a reason for this? I know this is probably TLDR :D
Great question! Did you have a specific correlation technique in mind? I'm thinking that cosine similarity might be better between the vectors (e.g., moving from binary to "product" counts), but then there's the problem of handling all the vector combinations (e.g., a rule using 4 "products" on the LHS and 1 "product" on the RHS.
Gosh Dave! You are just the best!! I wish you could be my mentor. Thanks so much for this. It would be really nice to learn how to do this with R. #TeamR

I ran the solver and it came back with Female and HasElderly as the best combo, with a lift of 2.53. Did I do something wrong?
Thank you very much for this content
If we only are looking for associations with those who've survived, could we clean up this data set to include only records where survived = 1?
Awesome, David! Do you have something like this excel for conjoint analysis simulation of scenarios?
Glad you like the content! At this time I do not have any content on conjoint analysis.
David, Great Content!, best explanation. By the way, what are support and confidence?
Thanks, Ajay! Glad you liked the video.
In a nutshell:
Support - The percentage of transactions in the data with a particular itemset. For example, using the Titanic data, the percentage of passengers that were both female and traveling in 1st class.

Great job, but isn't it easy if we use the correlation feature of data analysis?
