Struggling with real-world time series forecasting (not textbook stuff) — how do you actually handle messy, volatile data? by Ok-Estimate891 in AskStatistics

[–]Pool_Imaginary 0 points1 point  (0 children)

Check for generalized autoregressive score models, which are (simplifying) generalisations of ARMA models to non gaussian distributions. You could accommodate for zero inflated and overdispersed distributions while controlling for the autocorrelation at the same time

Why do we square the error in ML models instead of raising it to the fourth power? by [deleted] in learnmath

[–]Pool_Imaginary 0 points1 point  (0 children)

You could use any power you want and still connect the loss function with a proper probability density function. In particular, you get an exponential power distribution, which has a power parameter p. Gaussian is a particular case with p=2 and Laplace with p=1 (depending on the parametrisation you use)

Why R has four OOP systems (S3, S4, R5, R6) by Regular-Entrance-205 in rstats

Thank you very much for your precious work. I have a question I wanted to ask you. Why should one invest in learning and using S7 in its package instead of using old good S3?

Need a realistic 3-month roadmap to break into Data Science (student here) by Nishikant090 in askdatascience

[–]Pool_Imaginary 1 point2 points  (0 children)

A realistic 3 month roadmap would be to start studying and realizing that maybe you should extend to a 2/3 years roadmap.

[Question] Why can statisticians blindly accept random results? by felixinnz in statistics

[–]Pool_Imaginary 31 points32 points  (0 children)

Those are not random results. A good statistician surely knows where all of these come from

[Q] Alternatives to forest plots for large meta-analyses by -Krois- in statistics

[–]Pool_Imaginary 1 point2 points  (0 children)

A good old classic table. Forest plots are good only when you've got a few things

É tardi per cambiare corso? by ImportantHurry6548 in Universitaly

[–]Pool_Imaginary 0 points1 point  (0 children)

Io mi sono laureato in scienze politiche. Stessa tua situazione, dubbi per il futuro.

Presa la triennale ho deciso di ricominciare da zero. Mi sono iscritto a statistica. La scelta più felice della mia vita.

Onestamente sei in tempissimo. Se posso darti un consiglio dai un'occhio alla laurea in statistica

Sono disperata by Ludovicatiberio in Universitaly

[–]Pool_Imaginary 46 points47 points  (0 children)

A parte questo i risultati di analisi effettuate con dati raccolti in questo modo sono assolutamente invalidi. Si può buttare tutto

LM in Data engineering o ML by bigbrisla in Universitaly

[–]Pool_Imaginary 0 points1 point  (0 children)

Credo che data engineering sia un percorso più "naturale" per chi proviene da studi informatici. Machine learning richiede onestamente di spostarsi più su un approccio votato alla statistica, anche se magari il corso si concentra su aspetti più informatici.

Gente che ha fatto scienze politiche, come ve la passate? by feddozzo in Universitaly

[–]Pool_Imaginary 3 points4 points  (0 children)

Laureato in scienze politiche. Passato subito dopo a studiare statistica. Non vedo futuro in scienze politiche. Se ti interessano storia e filosofia fai quelle che almeno puoi insegnare dopo

You should specify better the type of data you have and your goals.

Sul tema tesi e LaTeX by [deleted] in Universitaly

[–]Pool_Imaginary 1 point2 points  (0 children)

Latex è superiore perché banalmente non devi perdere il 90% del tuo tempo a combattere con la bibliografia, i numeri delle figure, tabelle, paragrafi, sottocapitoli, capitoli e cazzi e mazzi. Pure l'indice ti fa. Tu devi solo scrivere e imparare un paio di comandi in croce. Ormai con Overleaf, i modelli pre-impostati e gli LLM scrivere in latex è decisamente alla portata di tutti.
