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?
View 5 RepliesI 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?
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:
0 0,0046
1 0,0033
2 0,0023
3 0,0017
4 0,0012
5 0,0008
6 0,0006..........
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.
=NORM.DIST(-0.7525,0,1,FALSE)=0.30057
I want to do inverse 0.30057 To get -0.7525 ,NORM.INV(0.30057,0,1) This function returns only cumulative distribution .
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.
View 2 Replies View RelatedI 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
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.
I have the following table:

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'm trying to find a way to make the user select only one of five columns in a row. What I’m trying to get is a ranking of 1 to 5. The user will click a cell and it will fill in or the user puts an X in it. In row 8 I want to select A through E but only one of them. If the user changes their mind and clicks another cell, the first cell clears.

I am working on a grading sheet for our company. I would like users to choose from an option button choice (A, B, C, D, F) for each grading category and I would like to write that to a sheet that corresponds with the graded person. The form will have next and previous buttons to move through the grading process - when previous is chosen I would like the option buttons to populate what was stored in the data sheet. I think I can mottle thru the code individually but with 60 option buttons it may take quite some time.
Can I call an option button choice by "Group"? I started coding individually, but it will take a lot of code - surely there is a more efficient answer. A picture of my form is attached at the bottom of this post.
VB:
Private Sub OptionButton1_Click()Dim Grade As String
If Me.OptionButton1 = "A" Then
Grade = "A"
Else
Grade = ""

I have 2 columns "H" and "I" from line 6 to 409. Each cell may start with AR , MA or a number. If cell H6 starts with AR I would like to put that cell into B6. If H6 does not have AR then I would like to check I6 for AR, and put that into B6 if it's found. If I don't find AR in either I would check them both for MA, and write the cell that finds MA into B6. If the AR or MA are not found then I would want it left blank. I did try
IF(FIND("AR",$H7,1),$H7,IF(FIND("AR",$I7,1),$I7,IF(FIND("MA",$H7,1),$H7,IF(FIND("MA",$I7,1),$I7," ")))) in B7.

View 6 Replies View RelatedI have a series of macros altering various workbooks and sheets. They're numbered Step1, Step2, etc. In my Step5 I have a series of Case statements in a macro, and I don't know how to get it to do what I want next. I have NOT tried running this code yet, and I'm sure I have something(s) wrong in it.
1) If the selection in DstWbk, sheet "Steps", is "01DSP" through "11DSP" the macro needs to delete specific columns in the SrcWbk, and then move to the next step (6).
2) If the selection in DstWbk, sheet "Steps", is "*DSP" the macro needs to go directly to the next step (6)
3) If the selection in DstWbk, sheet "Steps", is anything else the macro needs to flash a generic "No Data found" message and move on to Step7.
The part of the code that's throwing me begins at 'Select only the specific regional data' and ends at the "Case Else MsgBox"
I did a survey of what kind of clothes people like to wear and why. So there are two things that people have to write down. ex) jeans and cus they're comfortable / shirts and cus they look good
The data that I received was organized as followed
I just put in random things just so you can get the idea of whats what
Id
jeans
shirts
cardigans
[Code].....
Okay so what I want to know is how I can get the responses from the data spreadsheet I showed you before into this organized data table above.
I am writing a simple application that allows users to enter an item ID and execute a find. If the data is found, the UserForm populates with the pertinent data for the requested ID otherwise a message indicates Item not on file. The file being interrogated is an Excel workbook with multiple functions, unrelated to my task.
The problem: When my application opens the workbook to perform the Find, the screen displays a message generated by Excel, informing the user that the workbook contains links to other data sources and requesting to choose to either Update or Don't Update those links.
I used the Application.DisplayAlerts=False line but it has no effect on above. The choice I always make is Don't Update and the macro continues to the end without further ados.
Is there a way to either cancel such a screen request or automatically select a given option?

I was just trying to work around a problem with multiple UserForms in project. I have assigned Object variables oUserForm1 and oUserForm2 to represent UserForms of specific names.
VB:
Dim oUserForm1 As Object
Dim oUserForm2 As Object
Set oUserForm1 = VBA.UserForms.Add("Data" & CStr(X))
oUserForm1.Y = Y
[Code] .....
When oUserForm1 shows new data are inserted and another macro runs with a line to hide the opened UserForm.
In my project manager this user form name is i.e. Data1 (for x = 1), but the syntax Data1.Hide returns error. After that line it ask me to close the TOP most modal UserForm.
But When I use Me.Hide all works well.
My question is: Does VBA not see the name of the userform ("Data1") because I have used the oUserForm1 variable to give it a focus to it?
