I was expecting business sales forecast. but turns out to be a weather forecast. Thank you for giving me insights and ideas to what markov chains can do.
KINDLY HELP. "I have 4 umbrellas, some at home, some in the office. I keep moving between home and office. I take an umbrella with me only if it rains. If it does not rain I leave the umbrella behind (at home or in the office). It may happen that all umbrellas are in one place, I am at the other, it starts raining and must leave, so I get wet. a. Write the transition matrix."
A square matrix P = (ptj) is called a stochastic matrix if each of its row is a probability vector i.e. if each element of P is non-negative and the sum of the elements in each row is one.............BUT YOU SAYS THAT THE SUM OF IT'S COLUMN IS ONE......WHICH ONE IS CORRECT?
What sums to one are those ROWs, NOT the COLUMNs.(In my world of math) And we right S_n=S_0*T^n. please check wiki and commend this comment if you think its useful. WIKI: en.wikipedia.org/wiki/Stochastic_matrix Maybe you write it differently being Australian?
The transition matrix is fine. There are normally two notations for writing a transition matrix. Either having current states on the rows with the next states in the columns or alternatively like he has presented. Notice the summation is one for either notation.
This is wrong solution of this question. 0.2 should be switch with 0.4 last week this question was appears on my Stochastic Calculus Exam i used you technique for solution, but that was wrong and i loses my 12 marks. Delete this video because this misguide so many other students.
You made us understand not only the concept but also the practicality, tysm love u .
Very well-presented and clear. I especially like how you supplement the matrix explanation with trees--really makes matrices less abstract. Thanks!
Beautifully explained, Keep it up William

Excellent, today I've learned something new. Thanks for posting!
Great video, thanks for making it so clear! :)
Perfect presentation !!
Your voice is soothing 🎉is it Ai.. great explanation
Thank you. It was very nicely explained.
super helpful, thank you so much !
Thank you, sir!
GREAT IN SIMPLE WORD ....
The row sum should be 1, so 0.2 and 0.4 is reversed
@Rohan Patel I think it would be easier if all the world uses the same terminology. So far what I've seen are all written like State*Trans. Matrix.
great presentation, thanks mate
Very well explained
thank you so much for this videos!

Thanks for tutorial
KINDLY HELP. "I have 4 umbrellas, some at home, some in the office. I keep moving between home

umbrella behind (at home or in the office). It may happen that all umbrellas are in
one place, I am at the other, it starts raining and must leave, so I get wet.
a. Write the transition matrix."
is there a steady-state factor as we receive infinite amount of days?
thank you so much
Yeah I still don't got this
I loved the lecture
Thank you!
thank you so much. please make something for continuous and discrete time Markov chain
if today was cloudy not sunny, would the matrix change?
ILY thanks

Exactly, sum of the elements in a row is equal to 1 and the column is a vector
excellent
great
You should replace my Math teacher. She can't explain anything this clear.
And how do estimate the TP standard errors?
sir thank u
Please upload for periodicity. thnx

Same in Sweden, everyone do a bit what they like it seems like
can you lower the mic volume more? Now I'm deaf
I love you
Sum of rows for TPM at 6:56 is not equal to 1
Thanks a ton :-)
Sorry to say, but your transition matrix at 4.30 is wrong. :)
Ok, I'm not the only one!! The rows must add up to 1 not the other way around.
The transition matrix is fine. There are normally two notations for writing a transition matrix. Either having current states on the rows with the next states in the columns or alternatively like he has presented. Notice the summation is one for either notation.
thanks for noticing
@@awinoful thanks bro, really helpful, I was a bit confused
Watch 3:16
