    While simulating data, a distribution was observed, but the specific type of probability distribution was unknown. Your video provided the answer to this question. Thanks for your great video, you have gained a subscriber.

    This is really helpful for beginners like me. Going through all courses and have learned most concepts needed for data analytics.

    (16:42) 99% should represent the percentage of the data below 3, not above 3. Isn't it ?

      Good call. That is correct

    your videos are so helpful. if you add one or two real data analyst project to your videos, your package would be one of the best. thank you

    How can I find mean and variance of probability distribution using python? I have mentioned a problem below. Thanks in advance!
    The number of times I go to the gym in weekdays, are given below along with its
    associated probability:
    x = 0, 1, 2, 3, 4, 5
    f(x) = 0.09, 0.15, 0.40, 0.25, 0.10, 0.01
    Calculate the mean no. of workouts in a week. Also evaluate the variance involved in
    it.

    How to use on real dataset,as an example how would I know if one of my columns follows geometric or Poisson distribution?
    Also we can't do geomtric,Poisson test on any columns,right?

    Hello sir , please help me to find a solution of one of my question
    suppose x and y are random number uniformly distributed in the interval (0;1) what would be the distribution of z=x+y
    Please guide me how. To do this program .

  • @alexladda9076

    Why does the plot for the uniform distribution not rise/fall to zero below and at the min/max values? I would have expected the values outside the range to be zero and then a near vertical rise/fall at min/max? Is that just interpolation of the plot?

    • @DataDaft

      It is just a quirk of the smoothing of the density plot function that makes it look like there is a little bit of density outside of the min and max. There are no values outside the min and max.

    how would you do this
    Say you started a UA-cam channel about a year ago. You’ve done quite well so far and have collected some data. You want to know the probability of at least x visitors to your channel given some time period. The obvious choice in distributions is the Poisson distribution which depends only on one parameter, λ, which is the average number of occurrences per interval. We want to estimate this parameter using Maximum Likelihood Estimation.
    Simulate 100 visits to your youtube channel, assuming that they will a Poisson distribution with a mean of 10 visits per minute. Plot the arrival time vs visitor index.

    • @DataDaft

      You could generate 100 random exponentially distributed data points with lambda = 10, take the cumulative sum of those values to convert each arrival time into a vector of 100 successive arrivals and then plot them against the indices.

    Hey, I can solve this problem using the formula longhand with Python. Do you know an easier way to accomplish this with scipy? The problem is: What is the probability that the world series will last 4 games? 5 games? 6 games? 7 games? Assume that the teams are evenly matched.

    • @DataDaft
      @DataDaft  3 роки тому

      Not sure off the top of my head; for problems where I'm not sure how to set up the distributions to get an exact answer, I would generally just code up a simulation and run 100k trials or so to estimate the answer.

    How to create function for uniform distribution in python ?

    • @DataDaft
      @DataDaft  3 роки тому

      If you want random uniforms you can use the method shown in the video with scipy.stats or use the base python random module:
      import random
      random.random() # generate 1 random uniform

    Thank you for sharing
    Can you please provide coding with example for each distribution?
    Kindly guide me
    Or can you provide any source to study python for probability distribution please?
