I need a probability distribution for amounts to be shipped taking into account both the probabilty distribution on parcel sizes (amounts to be shipped) per ship as well as the probabilities on the number of ships arriving.
Please see the following:
Say you have a probabilty distribution for ships arriving, i.e. the probabilty of 1 ship arriving in a specific time period= 0.25 ( event a), the probabilty of 2 ships arriving = 0.2 (event B) etc. Please take into account that this can go up to about 20 ships per time period.
Each ship can have one of four parcel sizes, (demand that needs to be met) (the following are just example probabilties)
0 tons with a probability of 0.67 event 1
1000 tons with a probabilty of 0.08 event 2
1500 tons with a probabilty of 0.222 event 3
2000 tons with a probabilty of 0.022 event 4
Thus event a has a probabilty of occuring, in event a, events 1to 4 can occur with their respective probabilties.
I assumed events 1 to 4 stay the same for all ships arriving (as we are dealing with multiple products, each product will have different parcel size distributions, however I look at products seperately, thus only one product is considered here)
This is simple for 1 or 2 ships, but as the number of ships increase the number of combinations become excessively large.
Should i use a macro that determines permutations/combinations? I am kind of clueless on this one.
If it helps to put the problem in context; I am trying to determine a demand distribution as input for a stochastic programming model
I have two data sets one measured and one modelled and I am testing a conceptual model that proposes that only where the tails of the probability distributions of each data set crosses will you experience an event. I'm enclosing an example file which contains both data sets and some descriptive statistics as well as the associated histograms and a diagram of what I'm ultimately trying to achieve. My question is how I go from the data sets I have with such a large discrepancy between them to plotting their probability distributions?
This is more of a probability question than Excel - but I know Excel has functions to work out the answer (and I was hopeless with probability maths at school so knowing which function to use is also a problem)
Here's the deal: There are 43,000 tickets in a multiple draw lottery/raffle There are 1,730 prizes available. Each winning ticket is returned to the pool after being drawn, so in theory, one extremely lucky ticket holder could take home every prize.
However, what is the statistical probability (chance) of winning a single prize and what formulae/functions does one use to generate the answer?
I have a list of numbers in an Excel range. Most of the numbers are the same but some are not. I need a function that will go through the list and return the value which occurs most frequently. (Not the number of occurences but the actual value). I need to do this in VBA.
There is trading system which generates a winning trade per ONE stock in ONE month’s time with a probability of 5/12 (0,4166%). If the system trades 10 independent stocks the probability of any number of winning trades occurring out of all of them in ONE month is shown below:
None 0,0046 One 0,0326 Two 0,1047 Three 0,1995 Four 0,2494 Five 0,2172 Six 0,1272 Seven 0,0519 Eight 0,0139 Nine 0,0022 Ten 0,0002
I took these values from a book…I tried to reproduce these values in the spreadsheet that I attached. My table looks as follows:
I want to know if it's possible to calculate the probability that a certain range of values, reach to a certain point.....
The range is this (example):
4 3 9 7 14 22 15 20 42 46.....
What I want to know is if this tendency will reach to 1000. Or how many steps more will be need to reach 1000.
Like I said, and don't know if this is in the right place, but if you put this values in a graphic you will see that the tendency is growing. I assume that this tendency will reach to 1000. But will be in the next 10 steps or in the next 30.
I'm trying to make a bell curve (normal gauss distribution). I have some problems regarding the probability density curve, since its values are so low. If you look column N in the attached file - I used the NORMDIST command. Values should be somewhere between 0,2 and 0,4 - but they're about 100x lower.
Lets say I have 20 cells. I want to randomly assign a label to the each cell from 5 choices, like "Blue", "Orange", "White", "Green", and "Black". But I want to assign a probability of selecting the labels. So the percent probability of choosing Blue would be 56% and White would be 23%, etc. . . is there a function that allows me to do this?
my aim is to count the maximum occurrences in sequence of False statements before they are interrupted with a True ( in this case 2)
I can figure it out what method to use, Formulas or VBA? More precisely my VBA sucks I am trying to use excel functions by creating a counter with if() and then sum it but obviously it is a dead end.
Can anyone help, I'm trying to create some test data, eg 1000 rows in excel. In each cell a formula (?) returns some text such as Dog, Cat or Rabbit based on the probability Dog=0.5, Cat=0.3, Rabbit=0.2
I've come up with a messy solution of generating a random number between 1-100 and then using a lookup table where 1-50 = dog etc... it works but is long winded and difficult for other people to follow.
1. I need to randomly generate either a 1, 6 or 12 every time I hit calculate (i.e. F9).
2. I want to specify the probablility of each result. For example, I want 12 to be the result 80% of the time, and 6 and 1 to be the result 10% of the time.
1. First thing I am trying to do. I have a column of cells that have multiple values, some with text and some with no values at all. I want to be able to display in A1 the most commonly occurring text in cells C1:C15, and be able to display in B1 the number of times that A1 occurs in the same range. Below are the formulas that I am using. There are two problems that I am running into: First, the formula returns a #NA error if any of the cells in the range are left blank. Second, the formula counts the spaces or zeros, so if there are more blanks than the word “amber” then A1 returns “ ” and B1 returns the corresponding number.
A1 =INDEX(C1:C15,(MODE(MATCH(C1:C15,C1:C15,0))))
B1 =COUNTIF(C1:C16,A1)
2. Second thing I am trying to do. In A2 I want to display the second most commonly occurring text in the range, with it’s corresponding count in cell B2, and the third most in A3 and B3, etc
I am aware that I can use single changing events in worksheet change events. For instance, if column 1, or A is changed, do something. This is only a single If statement, i.e. either the condition is true, or not. What I am not sure is if I can use two changing events, i.e. two conditions. For e.g. I would like if Column A value is X and Column B is "Active", action it, but only if two conditions are true.
For.e,g. The below syntax does not work. If it is only column A, it does work, but I want both A and B to be true, then copy and paste the target does not anything.
VB: If Target.Column = 1 Then If Target.Column = 2 Then If Not Intersect(Target, Range("A2:A" & Rows.Count)) Is Nothing Then If Not Intersect(Target, Range("B2:B" & Rows.Count)) Is Nothing Then If Target.Value = "X" And Target.Value = "Active" Then
Each question is multiple choice (either A/B/C/D/E) and the values listed are the probability of each letter occurring. What formula would I need to put in the 'output' column for it in each row to output a letter based on the probabilities. E.g. in question 1, most of the time it would output E, but sometimes (rarely) A and very rarely B/C/D.
I have a excel worksheet with the following columns: First name, Last Name, Email address, domain of email, product type, date registered. The list consists of about 50,000 entries. I want to sort the list by the domain of email(which I am able to do already) Once this is done, I want to find all instances of where a domain appears at least 10 times on the list(such as webmessenger.com appears 40 times, so I want to get that data).
For those instances where the domain appears at least 10 times, I want to pull those rows out of the intial list and put them in a new list(the new list will be sorted by domain and will only have people who have a domain which appears at least 10 times). To make this a bit more clear, The initial list I have is a list of people who registered to use the software my employer makes. We are trying to locate companies which may have many people using our consumer version of the software. When there is a large amount of people in the same organization using our software, it would benefit them to upgrade to the enterprise version due to enhanced managment features. By running this filter, I can see which companies have at least 10 users registered to use our software. Of course I will remove any Gmail/yahoo mail/msn/hotmail... pretty much any public email domains and just leave the ones that are obviously corporate emails.
So far, I think it probably has to be done with a pivot table... I was able to get a table that tells me how many instances occur from each domain, but I cannot get it to display the actual data(it just says IE. company.com 200, yahoo 120, etc... I need it to show me the 200 rows of company.com emails and extract them to a new sheet so that I can then follow up with company.com and see if they are interested in the corporate version.)
I am trying to write a code where user has to respond to input box option depending on yes or no selection. There are two types of responses to different questions. One needs to respond between 1 and 100 (if yes) and for some other questions needs between 1 and 4 (if yes). A "no" will enter zeo value. But it is not working. I am using two named ranges "VALIDCELLS" (for 1 to 100) and "FREQVALIDCELLSS" (for 1 to 4). Here is the code;
But now I have to do let people also print a copy a regular way, without the macro I made before. But if they go through the regular way iof printing I would like to insert at header in red color, to notify them that this is just a preview and not the way to print. And here we come to the problem ....
I've created an addin to reformat spreadsheets that I receive in a particular format. What I would like to do is enable events so that whenever a spreadsheet is opened the reformatting procedure is run (this also validates whether the spreadsheet is of the correct format).
I have created a class module with the following code (exactly as the Excel help):
Public WithEvents App As Application
Dim X As New EventClassModule
Sub InitializeApp() Set X.App = Application End Sub
Private Sub App_WorkbookOpen(ByVal Wb As Workbook) SortE1Output 'This is my procedure that determines whether the 'spreadsheet is of the correct format and then reformats it End Sub
"After you run the InitializeApp procedure, the App object in the class module points to the Microsoft Excel Application object, and the event procedures in the class module will run when the events occur."
When I try to make a call to the InitializeApp procedure in the auto_open procedure (in a different non-class module) I get a "compile error: sub or function not defined".
I have a spreadsheet,3 columns are shown in the attached.The first column gives the date of the event,the second column the time and the third a rating.I want to put the average rating for each event in each cell in column 4.
