Add semi parametric survival analysis (Cox proportional hazards)

[FBartos]

adds semi-parametric survival analysis
Should the analysis be called "Cox proportional hazards" or "Semiparametric"
(later we will add "parametric models" (under a single umbrella because they can have many different likelihoods, similar to glms)
links: jasp-stats/jasp-issues#206 (does not add Bayesian versions)
the proper qml display requires commits pos 19.1

plotting completely switched from survminer to ggsurvfit due to a) patchwork and better flexibility

some nice data sets for testing:
Rossi.csv
Rossi.long.csv --- can be used for the counting input
bladder.csv

[FBartos]

@boutinb there are couple of qml bugs with the height of VariablesForm
could you check SemiParametricSurvivalAnalysis.qml the for // TODO: Bruno

[juliuspfadt]

why can this PR actually be merged without my approval? Shouldn't there be securities that there needs to be some contingency?

[juliuspfadt]

I think the name "semiparametric" sounds good

[juliuspfadt]

So when I choose Counting with the Rossi.csv data, the GUI fucks up. Same with the RossiLong data

[juliuspfadt]

When Method=Exact and some variable is put in Cluster, I get an not very informative error:
error1.jasp.zip

[juliuspfadt]

Another error, the tables are all empty for the specific combination of options:

error2.jasp.zip
I assume that is because theta is by default 0 (same for Df by the way) and likely makes no sense. If you think people will know for sure that this is the reason and they will not look somewhere else what could have caused the empty tables, then I think it is fine. If there is the slightest doubt and users are as stupid as me, you should at least add a footnote beneath a table.

the hazard estimation table shows weird numbers for this
error3.jasp.zip

[juliuspfadt]

I dont get why the Plot has Options Legend and Color Palette. For me, I do not see a legend nor colors. It's a grey plot. Maybe I am misunderstanding something.

[juliuspfadt]

I get some plot errors with this:
error3.jasp.zip
Happens for residuals plots type Score, Schoenfeld, Schoenfeld scaled

[juliuspfadt]

where are the tests? and where are the help files?

[juliuspfadt]

Quite the big PR, nice work, especially coding the conditions in qml as a function. I am going to steal that!

[FBartos]

all but the UI is fixed now

[juliuspfadt]

the hazard estimation table shows weird numbers for this error3.jasp.zip

did you check all these errors. Cause this one seems to be still there for me.

[juliuspfadt]

most of it seems fine, but not all :)

[FBartos]

fixed the remaining issues

[juliuspfadt]

I should start working with the info stuff in qml, nice.
The last error is fixed for me. Not sure about the description file, did ou update the version? Although, most of my modules are a bit behind either...
