Thanks for the video it helped me. I have bit different situation here as I have 2 inputs (Raw data and mapping file in which I used file browse tool ) and the output file (used file browse tool). Now I have to use the output file(coz there is some manual intervention is required in the data) as input data in next step and the final output should arrive but in user interface it is asking all 5 inputs in one go (Raw data, Mapping file, Output data path, Input the output file again, and the consolidated output. I am not able to achieve this in alteryx. Can you please help. Looking forward to hear from you.

Hi Sir, thank you for your tutorial. I did data imputation on my small size(n=46) dataset and now need to do exact logistic regression by "elrm" package of R studio. fof is my dependent binary variable, age is numeric and predictor, injuries is binary predictor, minutes and mental health are continious predictors, and race is categorical with three groups. But my code fails because it does not recognize one part "n". I searched in online examples, They did not mention what this n(number of binomial trials) is and how they added this column to their datset. my code: data.elrm <- elrm (fof /n ~ age+ injuries + minutes + mentalhealth + rece , interest = ~mental health, iter = 20000, burnIn = 500, Dataset = imp) Do you have any suggestions for me ?

Good explainer Re: using mice. However, in addition to @annap9782's comment, I'd also flag that finding that your imputed data is distributed similarly to the observed data is not a meaningful test of imputation performance. If we had a (conditionally) ignorable missigness mechanism (i.e., MAR), it may even be expected that these distributions will differ, without this saying anything about the performance of a given imputation.

Thanks. I have Selected based on the correlation and closeness of the data to original set.. there are a couple ways to this. Some don’t choose the data for substitution but just use it for analysis…
@christophertauss3640

Well done. A very simple case (those are the best for these kinds of instruction videos) that says in a concise way how to use this very powerful feature of Alteryx. The one thing I would have liked to see is how to configure the text box so only Male or Female (and maybe Other) is an allowable entry. These UI elements do typically need data validation. But great job. I am building an Alteryx workflow myself and adding a UI element similar to above, and you saved me a lot of research and looking around.

It doesn't seem too efficient to keep updating all rows... In source table you should have a column: RevisionDate and set a trigger on this to auto update. Then filter on this column.

and if you dont have any column modified date, you can compare all columns with except command of sql ? do you have any better idea for me :) ?
