Question

when doing Anderson Darling test for Weibull distribution, how to get gamma, beta, and alpha.

note :

I am using Excel.

Answer #1

I guess in the basic excel you wont get Anderson Darling test.

in order to test the same using excel you must need some extra plug in package ex - real statistic, RCP package

Using Real Statistic package following are the commands you can use to get the parameters desired,

=ADTEST()

=GAMMA_FITM()

I have given you example for gamma also please refer to that,

For the data below, use Anderson-Darling test to see if it
conforms to a Beta distribution with shape1=4, shape2=7. What is
the p-value?

In a General Social Survey, respondents working full time or
part time reported how many hours they worked in the previous week
at all jobs. The random sample of 1,729 produced a mean of 41.8
hours with a standard deviation of 14.6 hours. Using these data
what would you conclude in a test of the following hypothesis?
Ho: M = 40 hours
Ha: M > 40 hours

I am trying to figure out how to find the test statistic using
Excel. I understand the formula- that I need to use parameter 'p'
and 'normal distribution' ….z= sample proportion and minus the
'population portion' then we divide p*q and divide n -sample size.
I understand how to populate the data in the formula. I just can't
figure out how to solve this using Excel. (my only option with my
class) I need step by step directions if possible....

Point estimates often need to be nested in layers of analysis,
and it is the Invariance Principle that provides a pathway for
doing so. An example would be estimating Mu after having to
estimate Alpha and Beta for some distributions. In simpler
statistics class exercises (like those we've seen up until now),
this is typically avoided by providing the lower level parameters
within exercises or problems (e.g. asking you for Mu by giving you
the Alpha and Beta). The only...

(1) Using a generator for a binomial distribution, we will test
the results of Example 3.8.2. Using software generate 500 random
deviates for X from a B(10, 0.3) distribution and 500 random
deviates for Y from a B(5, 0.3) distribution. Add corresponding
random deviates from each distribution to form an empirical W=X+Y.
Then use the theoretical result of Example 3.8.2 and directly
generate another 500 random deviates for W from a B(15, 0.3). Order
the result of the sum of...

T F 1. A p-value of .008 in hypothesis testing means there is
only a .8% chance we could get such sample statistics from the
population if the null hypothesis is as stated. Such an event is
considered unlikely and we would reject the null hypothesis.
T F 2. As a general rule in hypothesis testing, it is always
safer to set up your alternate hypothesis with a greater-than or
less-than orientation.

T-tests are used when you want to examine differences but you do
not know everything about the population. There are three types of
t-tests that you may choose to do: one-sample t-test, independent
sample t-test, or dependent sample t-test. You can calculate these
by hand, in SPSS, or in Excel. The instructions below can be used
for SPSS and your textbook offers instructions for using Excel.
Single-sample t-tests
These tests are used when you want to determine the
probability that...
