True.

I recently discovered your channel and I must confess that it has been super resourceful. I have had trouble understanding some theories and concepts in statistics. Mind you, I have been done with Uni for years. However, because I want to purse a career in Data science which requires having fundamental knowledge of some area of statistics makes it an evitable challenge that I must overcome in order to excel in this desired field. Great Job!

Amazing lesson! thank you! I found a difficulty in the material but you made it really easy!

Very useful! Thank you very much! You saved me hours of trial and error trying to figure out what this kind of problems were about!

I am so glad I came across this channel. Math generally isn't my best suit, but I am so happy youre helping me get there!

I believe you made a mistake towards the beginning when calculating the value for lambda. You wrote "lambda = 1/lambda" instead of "lambda = 1/mu"

Hello your channel is amazing and I never go to any other tutors to understand my problem but please do explain when we use each distribution as there are many of questions they don’t tell you the distribution type so you have to guess and stay in doubt and also when you are calculating lamda or mue too many books has introduce it in different ways and it is so confusing so when we have the mean please clearly explain how we can calculate lamda thanks

Since the question asked BETWEEN 4 and 7 years. We can only use the differences between the area less than 7 and the area less than 4 to calculate the answer. (7:00) I believe e^-0.8 is the amount greater than 4. It makes no sense of differences between (the area less that 7) and (the area greater than4). If I have any errors, please correct me. Thanks

Statistics is very difficult and really confusing and too much information are given so please do explain the formula of getting lamda from the mean and also in one of your videos you calculate lamda=1/lamda ?? Is it 2/lamda or 1/mue ? Or mue=lamda time t ???

its has been an amazing lesson thank you

Hi, brother. I think you meant: Now, the rate parameter is going to be 1 over miu, not one over lambda

Great video, helped a lot, greetings from Sweden!

Another great video. Thank you. I was, however, hoping you would include an example question that involves the less than and equals sign or more than and equals sign. I thought that if we wanted to know the probability of a laptop lasting a week or more (which each event being a day), we could simply make x=8 and use the greater than sign but it doesn't seem to be right.

@TheCoKeys

4 жыл бұрын

Kinda late but just in case when the less than and equal or more than and equal signs are used in distributions that are continuous(i.e. not discrete) it is essentially irrelevant and it is calculated the same way as if it was just a regular bigger than or smaller than 'x'.

You have been a life saver dude

As always, you're the best. TY.

Hi for part (e) shouldn't x be Greater than 4 and less than 7, was that a mistake?

Amazing tutor video, only thing I feel like you should be following more "standard practice" that mathematicians use, like when you show us P(x

btw you can also calculate the area under the curve with integrals since we know the formula

I have a doubt is that shoukdn't we be doing integration using the given years/time as limits?

I'm having trouble understanding the probability density function for the exponential distribution. What does it mean to say that the event at time=0 has a positive probabilty? I had thought that no event occurred at that time, so its probability should be zero. Why not?

@ryanjackson0x

2 жыл бұрын

Time=0 is when we started measuring. In this example I believe it is when all of the laptops are functioning properly, and as time progresses, they start failing with a rate given by the distribution function.

@larryschwartz478

2 жыл бұрын

Thanks very much for your reply. I had already looked into this further. My question to you was about the continuous exponential density function, although I had not mentioned it because I usually think in terms of continuous densities. I have discovered that for any continuous density P, P(X) = 0 for all X. I had never thought about this before. It reflects the fact that in a continuous density, X must be defined exactly. If X is, say, weight, and we ask what is the probability that someone's weight is 150 lbs., the continuous density will give that probability for exactly 150 lbs. However, no one weighs exactly 150 lbs. so P(150) = 0. But the probability of someone weighing between 150 lbs and 150.1 lbs can be obtained from the cumulative probability density of P. So, for a continuous exponential distribution, the probability of an event occurring at time=0 is really 0 because, literally, no event can really take place at time=0. But if we really mean the short interval between time=0 and time=30 seconds, then we can get the correct probability from the CDF. I learned a great deal from your video and the extended search it led me to. Thanks again, Larry Schwartz

are the formulas applicable whether the interval is inclusive or not?

@Peter_1986

Жыл бұрын

Yes, they should be applicable, because in this situation you are calculating continuous values, and one single specific value has a 0 chance of occurring, since it is one out of an infinite number of values. So "x ≤ a" and "x < a" would actually mean the same thing, since P(x = a) = 0.

@@teja1853 The PDF is used to calculate a single point (height) above the curve.
