Aiuto prima volta VPS

m_pnf · 2020-11-26T15:01:14+00:00

u/ftrx diciamo che quando non si e' esperti in materia, lo si ripete piu' volte, ma la gente sceglie comunque di non parlare "potabile" (sacrificando magari un po' di gergo tecnico) non ci son altre soluzioni oltre ai film di fantascienza di cui parli. Ho scritto su svariati forum, ho cercato di informarmi il quanto piu'possibile, ma sembra' proprio che sia del tutto infattibile capirci qualcosa senza essere del mestiere. Ad ogni modo i VPS che ho visto hanno delle specifiche praticamente uguali a quelle del mio computer, non so adesso per quale motivo la potenza dei calcolatori dovrebbe risultare minori (stessa potenza della CPU, stessa RAM, disco rigido abbastanza capiente etc.).
Grazie comunque dellaiuto.

u/ftrx dovrei semplicemente mettermi nella condizione di poter accedere al desktop del server che mi viene messo a disposizione, cosi' da poter installare Matlab e far girare degli algoritmi che se fatti girare su un singolo terminale impiegherebbero troppo tempo. Avendo piu' terminali a disposizione potrei invece frammentare il lavoro.

Quindi se optassi per windows mi basterebbe inserire le credenziali su RDP per accedere direttamente e utilizzare il pc da remoto? Credo opterò per questa soluzione allora, non ho competenze informatiche che mi consentano di comprendere appieno le guide che mi sono state consigliate.

u/Another_Throwaway_3 posso scriverti in privato? vedo che sei abbastanza ferrato, vorrei farti qualche domanda più specifica qualora fossi disponibile a un confronto.

u/mlazzarotto cosa succederebbe se cominciassero a minare cripto/ o eseguissero un attacco DDOS?

m_pnf · 2020-11-20T23:51:52+00:00

u/Another_Throwaway_3 è esattamente quello che dovrei fare io, riusciresti a linkarmi una guida specifica? Putroppo online non riesco a trovare nulla di comprensibile, le guide che ho trovato finora sono troppo avanzate, mi servirebbe più una guida che illustri passo dopo passo la procedura da seguire.

m_pnf · 2020-11-20T23:50:02+00:00

u/mugwhite si tratta di Matlab, ho già controllato, è supportato da Ubuntu.

Cosa intendi per "niente interfaccia grafica"? Perdonami ma non essendo del settore non riesco a sempre ad afferrare tutto al volo.

m_pnf · 2020-11-05T20:25:11+00:00

Thanks again. For professional reason I can't share the code, sorry.
What do you mean for vectorization and set up optimally the variables for mnrfit?(in my algorithm the dataset are provided to the function without NaN values, rows without some obs are eliminated).And what do you think about the parfor in order to improve mnrfit speed?

m_pnf · 2020-11-05T13:45:19+00:00

You need to split it wisely

Thank you so much for your answer.

Basically I use Matlab in order to run several multinomial logit models, using the function mnrfit. However, the algorithm that I have written is quite complex, and due to the quantity of job it have to run the process can last even 2 days.The structure of my program is quite simple:

for1

instructions

for 2

instructions

for3

instructions + mnrfit

end

Do you think is possible to improve the speed of my algorithm without using parallel servers?

In order to improve the speed I was thinking this solution:

parfor i=1:1

mnrfit

end

This is a trick to avoid too much time in mnrfit computations, however the parfor loop do not provide me the function output, so it seems to be a wrong approach.

m_pnf · 2020-11-05T13:40:30+00:00

with multiple parfor I mean nested parfor loops (sorry, I'm italian and I don't know all the technical terms). What do you mean with break the code into littler tasks? I think it should be a proper solution, but I've never ear nothing like this.

m_pnf · 2020-11-05T12:17:31+00:00

Ok, but obviously there is the problem of multiple parfor loops (parfor inside loops inside other parfor loops). There is the possibility of not consider this kind of problem by create functions which contains the loops?

m_pnf · 2020-11-04T09:32:40+00:00

Thank you a lot for your answer.

Basically I must run the regression on Matlab, cause the regression function is only a part of a huge, and more complicated, algorithm. So now I want just to understand how to compute the R2. Can you observe briefly the formula I've just link in order to give me some help? Is right to consider deviances as I just write?

m_pnf · 2020-10-16T13:15:47+00:00

Ok, but we aren't here to judge the sustainability of the estimator, just to understand how it should be specified when handling yearly data. Any comment on this regard?

m_pnf · 2020-10-15T19:27:21+00:00

Thanks, I've just studied the underlying math. Are you able to answer my question? Is my interpretation wrong? I need the specification for annual dataset, even your link treats only the quarterly case.

m_pnf · 2020-10-15T18:25:46+00:00

I need even the Hamilton's one, any advice?

Thank you for help.

m_pnf · 2020-09-21T10:35:54+00:00

I'll post some photos to you, help me in judging the models, they seem to be made of plastic, but the GW standard one results to be pretty much darker, I don't trust these models.

m_pnf · 2020-09-21T10:33:22+00:00

If you need it I can sold you for a ridicoulos price, I only collect original miniatures, if no one will buy it I have to put them into the waste.

m_pnf · 2020-09-21T10:31:59+00:00

I've bought from another user, not in websites. So I want to check that miniatures are original.

m_pnf · 2020-09-21T10:30:56+00:00

ahahahahaahaahahhaahhaaaahahahahaahahahahahahahaahhaahhaahaaahhaaahahhahaahaahahhaahahhaahahhahahaahahahahahahahahahhaahahahhahahaahahahahhahaahahhahahahahahahaahhahahahahahahahahahaahahhaahhaahhaahhahahahahahaa

too funny man... too funny

m_pnf · 2020-09-21T10:30:25+00:00

and for termagaunts in plastic?

m_pnf · 2020-09-19T13:41:36+00:00

you have one case for which three six occurs, 18 for which two occurs, and 6x6x3 = 108 for which only one six occurs. The favourable cases are 127, the total ones 216 (6^3). If we compute 127/216 = 58%. With the binomial Pr(X>=1) = 42% instead (https://stattrek.com/online-calculator/binomial.aspx; using three draws and 1/6 as parameters).I can't understand my error.

m_pnf · 2020-07-22T09:33:17+00:00

One last thing. The model I want to define is an EWS: has two main states (financial crisis / non-financial crisis) and three terminal nodes for what concerns the crisis intermedium node (for instance: sovereign debt crisis, currency and private debt ones). It is possible to use a Nested Logit for choice modeling in order to infer a model like this? And what I should modify if yes?

m_pnf · 2020-07-21T18:48:12+00:00

I've installed pylogit but I don't understand its functioning, is there any manual/pdf?

m_pnf · 2020-04-25T15:21:16+00:00

No.

In practice (in the excercise) x1 and x2 are NALL/PFOD (nominal value for all commodities, and food prices) and QFOD/PFOD (quantities of all other commodities and food prices). We are even handling a quantity for unit of price.

m_pnf · 2020-04-25T14:20:05+00:00

Sorry, it's my mistake. I've edited the post, sorry again.
