exercises for Weeks 13 (Mon Nov 10ff) and 14 (Mon Nov 17ff)

Thanks to our four wondrous PhD candidates for their intriguing presentations. I am also satisfed & grateful for your efforts with the OBLIG. I've placed com205c on the page, with mcmc for plants, Oblig #3. You may play with the code a bit to check further issues.

From Mon 10 onwards we're partly in repetisjonsmodus, looking back at what we've learned, etc., so please come with questions, themes you would like more comments on, etc.

We also go through:?

Exam 2015, #1, two models; Exam 2018, #1, poisson-gamma and more; 7.20; 7.29 (i).?

I'm uploading com217b, for Bayesian kriging, Gaussian processes (part of Ch14 terrain): how to interpoplate Z(x), with uncertainty, when it is only observed in a few positions. 

Mon Nov 3: PhD twenty-minute presentations no. 3 and 4!

Nex: 
Exam 2013, #2, Rayleigh. 

Oblig 2021, #3, Galton 1889, 111 husbands and wives (and their temper). 

Exam 2013, #3, do the data come from f_0 or f_1?

copulae

Berit used "copulas" in her presentation, but I prefer, of course, copulae (sorry, can't get this in neat table format here): 

Case    Singular    Plural    Meaning
Nominative    copula    copulae    the link / the links
Genitive    copulae    copulārum    of the link / of the links
Dative    copulae    copulīs    to/for the link / to/for the links
Accusative    copulam    copulās    the link (object) / the links (object)
Ablative    copulā    copulīs    by/with/from the link / by/with/from the links
Vocative    copula    copulae    O link! / O links!
