LearnNormalDistribution and LearnBinomialDistribution

[jricoiii]

Is your feature request related to a problem? Please describe. n/a

Describe the solution you'd like Would like to see the following features added

• re-scaling of height of PDF For N(0,1) For N(50,10)

• store the original parameters, so when changing tabs for different probabilities, you don;t need to re-enter the parameters

• ability to enlarge/full screen the created PDF? (also requested for LearnBinomialDistribution)

• ability to set x-axis (also requested for LearnBinomialDistribution)

• ability to increase sample size past 999 for LearnBinomialDistribution

• maybe increase the width/plot size for Probability Plot for Binomial (so it fills the space similar to the normal distribution, right now the graphic only fills the left half of the container for probability plot)

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.

Additional context Add any other context or screenshots about the feature request here.

not sure - was this fixed?

No, no changes yet on the distribution components.

Comments on the individual points raised:

1. I don't think we want re-scaling of the height of the PDF unless you mean that the user should be able to adjust the zoom. Reason being that we want to show how the tails get fatter or narrower, which works best when the y-axis stays the same. In the extreme case where the axes completely adjust, you end up with a situation where the shape of the PDF looks the same no matter what.
2. Should be doable.
3. and 4. Yeah, would make sense, will need to check how much work that would entail.
4. Will change the default maximum of 999 and make it configurable. That's certainly the easiest change from the list.
5. Reason for the whitespace is that the distribution widget can also display the distribution step function, and we don't use up the entire space when it is hidden. Will reconsider.

1. I agree that if re-scaled all normal dist look exactly the same. Already the x-axis changes as sigma gets bigger or smaller

• comparing tails is difficult since you are only able to see one distribution at a time (ENHANCEMENT IDEA - maybe be nice to overlay to 2 distributions - add to the component an option to create an additional normal distribution PDF, so user can more easily see difference - since the comparison of the two is visual - I'll add a new issue for this).

• My suggestion was really about just being able to increase visibility of the PDF, especially when finding probabilities - since when sigma is large the PDF is so narrow it is hard to see the area under the curve and can be misleading (being able to zoom into a region would be great)

5. Just was suggesting if the CDF option is set to false, you could change the width of the PDF
