@MichaelSumner-cs7gc - I was an R user and a huge fan of ggplot2 for many years. Not surprisingly, I've always preferred plotnine and have asked Microsoft to include it in Python in Excel. I use seaborn right with Python in Excel because it is better matplotlib. Hopefully Microsoft will get plotnine added soon!

Hi Dave on Data. Incredible, your site is just what I was looking for. Python in Excel. I have been using Excel for a long time! Mainly, for data collection, transferring to Statistical( Minitab, SPSS, Excel and R)and visualisation packages( Surfer and Grapher). I started with Lotus 123! I still do data interpretation using those tools and they are really time consuming. Most of my data are historical river water quality analysis and sediment transportation data. I will do your Python Crash Course. Thank you for sharing your knowledge and expertise.

Love the method chaining with assign - I'm always looking for new tips! Only difference in my workflow would be to shift the lines within the chaining parens to be under the new object with an indent to better use that white space as linters yell if lines get too long. Not sure if that's 'standard practice', but I like that pattern.

@DIGITAL_COOKING-I'm not sure what you mean by "use pandas in power query." Python in Excel is currently designed to have limited functionality (e.g., for Security reasons). At this time, Power Query becomes the primary conduit for feeding data to Python in Excel (e.g., from a SQL Server database).

Hey David, Do you think that Multiple regression will do all of this analysis for you by finding which variables has the highest correlation with the results being survival rates? If yes, then what are the disadvantages that are masked when using multiple regression directly without analyzing the data?
@DaveOnData
@DaveOnData 28 күн бұрын
@-Hussainnn - The mighty Analysis ToolPak in Excel allows you to easily create correlation matrices. There are two primary issues with relying on correlation (Pearson's is the default, which I will assume here): 1 - Correlation assumes a linear relationship with the data. However, the calculation can be misleading. Google "Anscombe's Quartet" to learn why you should always visualize your data. 2 - Categorical data can be problematic. Enter visualizing your data.
