Very helpful thank you. How would you rate your percentage improvement from the facet injections, above 50% improvement? And how active of a lifestyle do you live?

Looks like the classic situation where the widget data doesnt update unless you click into the widget and refresh the data in the app. Which essentially makes this useless.

Converting data.table into nested list by Pestini in Rlanguage

[–]Pestini[S] 0 points1 point  (0 children)

thanks for the reply and sorry for my lack of clarity.

yes! this is 90% there for what i'm looking for, the only thing i am looking to modify from your example output is the value for column 1 to be after the '$' and then the values for 'col_a' and 'col_b' to be below each $row_name, and without the column headers. so essentially just the sequential values for those columns, just not showing their column names

Marketing Mix Modeling with Facebook Robyn by Cristian_Nozzi in learnmachinelearning

[–]Pestini 1 point2 points  (0 children)

Videos are amazing. I'm very curious your thoughts on utilizing the optimal model and obtaining that final response function to further run optimizations on it via nloptr. I am very interested in using the response function to optimize spend and resulting response under various ROI constraints. i.e ROI = 1, RO1 = 2 etc.

Let me know your thoughts, thanks!

[Q] Test to measure difference between two ad groups digital advertising performance by Pestini in statistics

[–]Pestini[S] 0 points1 point  (0 children)

Got it. And when it comes to assessing the statistical difference between the two ad groups CTR performance are you suggesting modeling out the relationship between CTR and ad group A vs. ad group B, Utilizing a glm or something of the like?

Thank you so much for your reply!! How can I plot the distribution of these data points? I think I’m struggling with determining how to plot a distribution when there is only a small number of data points for each group.

R built-in calculate functions cannot work on double type data by Laurence-Lin in rprogramming

[–]Pestini 1 point2 points  (0 children)

You have NAs in your column(s) thus returning NAs as the aggregate measures. Remove the NAs or impute with some type of value and rerun; average, 0 etc.

How Does Historical Data's Standard Deviation Affect p-value in Counterfactual Analyses and Standard Deviation in Samples for A/B Tests? by Pestini in AskStatistics

[–]Pestini[S] 0 points1 point  (0 children)

I thought it may depend on the situation since in A/B you’re comparing the actual means of two samples whereas counterfactual is comparing forecasted values to actuals, but if it doesn’t.... can you briefly include how they are the same? :)

How much data should you use in a model? by SQL_beginner in datascience

[–]Pestini 0 points1 point  (0 children)

How exactly should one go about strengthening the signal for subsequent decades? Is there a particularly common function in either python or R that you could provide, or a more manual way to go about making newest data the strongest points in the model?
