The objective is to estimate the fairness of the coin.
Below is a table representing the frequency of heads: We know that probability of getting a head on tossing a fair coin is 0.5. An important thing is to note that, though the difference between the actual number of heads and expected number of heads( 50% of number of tosses) increases as the number of tosses are increased, the proportion of number of heads to total number of tosses approaches 0.5 (for a fair coin).
This makes the stopping potential absolutely absurd since no matter how many persons perform the tests on the same data, the results should be consistent. I) are not probability distributions therefore they do not provide the most probable value for a parameter and the most probable values.
These three reasons are enough to get you going into thinking about the drawbacks of the . From here, we’ll first understand the basics of Bayesian Statistics.
This experiment presents us with a very common flaw found in frequentist approach i.e.
being applied to numerical models to check whether one sample is different from the other, a parameter is important enough to be kept in the model and variousother manifestations of hypothesis testing.
Prior knowledge of basic probability & statistics is desirable.
You should check out this course to get a comprehensive low down on statistics and probability.
Bayesian Statistics continues to remain incomprehensible in the ignited minds of many analysts.“Bayesian statistics is a mathematical procedure that applies probabilities to statistical problems.It provides people the tools to update their beliefs in the evidence of new data.” You got that?With this idea, I’ve created this beginner’s guide on Bayesian Statistics.I’ve tried to explain the concepts in a simplistic manner with examples.
