Regression Learner App does not recognize array or table as valid input, "Start session" button remains grayed out

I have an array of numbers with the first 6 columns representing inputs and the last column representing the target. A few NaNs are present, but no column is all NaNs. I wish to perform regression.

When I start the Regression Learner app, the dialog box asks me to select the data for import. Once I select that, its name appears at the top. But nothing appears in response or predictors boxes below, and the "Start session" button remains grayed out.

I cannot get past this point. I tried importing a table instead (again, all doubles) with no success. All of the data are simply numbers.

Can you provide the output of 'version' command? Also, did you try the app with other/random data?

R2019a update 9 (.6.0.1472908) on a 2015 Mac PowerBook running Mojave 10.14.6

The problem is intermittent. I got it to work on the same kind of data for a while, then it simply stopped accepting inputs.The data are an approx. 5000 x 6 array of doubles.

Thanks,

Do you have any third party window-snapping applications running in the background? For example, Magnet, BetterTouchTool, HyperDock? If so, try disabling them and restarting MATLAB.

[Kevin Johnson]

No.

Given that it worked for a while, it must have been caused by another application running in the background. Try disabling/uninstalling any software that you installed recently.

I haven't installedany newsoftware in quite a while, other than updates to things.

Thanks for looking at this for me. I'm moving beyond this to other tools, since this doesn't work for me.

Hello,

I have a similar problem.

When I start the Regression Learner app, the dialog box asks me to import the data set variables. Once I imported that, I cannot import the response (it remains inactive/grey) and "Start session" button remains also inactive/grey. This problem was intermittent but is now recurrent since last week (while data are exactly the same).

If anyone has recommendations, I am intestered in!

Thanks in advance,

Cindy
