Predict Value Based On Weighting Of Prior Months
Dec 28, 2011
I have 11 months of sales commission data, and need to estimate the value for December. However, the catch is, for the first 7 months, the values are significantly higher than the most recent 4 months. I'm currently using the TREND function to guesstimate the December value, but with the wide fluctuation between the 2 time periods, I'm thinking the result of the TREND value may be way off.
Is there a way to 'weight' the data to reflect the higher values earlier in the year, with the much lower values later in the year?

Phasing Design.xlsx
We have a requirement to spread/phase amounts over multiple columns (representing months) using a weighting (represents working days per month).
We will calculate the weighting result in excel first (represented by a % per month), so the macro will be more of an allocation of row amount against the equivalent column %.
So far i have the following code:
VB:
Sub phasing()
Dim SourceA As Range
Dim Weight_ResA As Range
Dim TargA As Range
Dim i As Long
[Code] .....

My goal is that the formula in this named range references the prior 12 months. This does reference a twelve month range in my workbook, but not the prior 12 months based on this month being MARCH.
DATES =INDIRECT("sheet1!A"&MONTH(TODAY())+1&":A"&MONTH(TODAY())+12)

I have a list similar to the below:
#....|Name.... | Weighting %
1Artur Boruc 1
2Igor Tudor 5
3Alessandro Grandoni 3
4Gian Elia Amoretti 3
5Olivier Kapo 12
6Kim Källström 13
7Emiliano Bigica 13
8Julio Baldivieso 12
9Fabrizio Miccoli 13
10Peter Vougt 14
11Massimiliano Esposito 12
What I want to do is randomly select either number 1 to 11 (leftmost column OR the person it represents) but also make the selection based on the percentages in the rightmost column. To illustrate using the above example, Number 11 (Massimiliano Esposito) should have 12 times more chance of being randomly selected than Number 1 (Artur Boruc)...
I have used a formula such as
PHP
=INDEX(A$1:A$11,INT((RAND()*11)+1),1)
to randomly select a cell but how would I modify this to include cell weightings? Or is there a better formula?
An additional note I have is that the weighting for each person will always be changing, but will always be a percentage.

I have a list of products that I want a message to appear prior to printing based on the description choosen.
Product descriptions are choosen in D25:D34 via a drop down.
My wild cards are SWING GATE and DOUBLE SWING GATE, I want to use wild cards because of the many different sizes of each gate.
Private Sub Workbook_BeforePrint(Cancel As Boolean)
If Range("B" & Target.Row) = "swing gate" Or Range("B" & Target.Row) = "double swing gate" Then_
MsgBox (Range("F5").Value) & ", Please include chain and locks with order", vbOKOnly, "Chain and Locks"

I'm creating a form with drop downs, and I'd like the answer choice someone makes for one question (ie- what county they're in) to affect the answer choices for a secondary question (ie- what city they're in).
I'd like to avoid using names, at least for the second dropdown (since there would be too many names, and in some of the questions in the data set things change too much for names to be a good option). I would also like to avoid using VBA to keep it simple and maintainable. Here is a simplified version of a small subset of the data.
Drop Down 1:
County (options: Santa Clara County, Napa County)
Drop Down 2:
Cities/Towns (options: the cities/towns that relate to the above county selection, without using names)
County
Cities/Towns
Santa Clara County
San Jose

I used three different dates. In which the outcomes were available. The first three sheets.
Is there a possiblity to use excel to calculate a future outcome of the next month(Sheet 4). The figures are in a way linear, because the previous months are in it.
So it's possible for the future outcome to go up or stay the same. It can't be less then previous months.
See attachments.
It's about a holiday (combinations) of arrangements. So it'll be influenced by the date (because of holliday plannings), finance etc etc. But the last factors/variables we will use and test in SPSS and other programs.
The question is more: Is there a program/formula in excel which will predict the outcome in the last sheet with maybe a factor of outliners (this coincendence of a better salary in some parts/or the date that people will book a holiday). And how the formula would be formulated in the last sheet?

So I have some stats I have been tracking for NHL hockey games. I want to find a formula that is predictive of future outcomes, based on whether or not a team has a statistical advantage. Obviously, there are so many other factors, and there is no golden formula to accurately predict the winner of ever game. I want to find maybe a 70% success rate here. I want to be able to plug in all of the stats, and essentially have it tell me who statistically should win the game.
I have 11 independent variables (Stat A, B, C, D, E, etc.). I have a running total of how often the winning team had the stat advantage for each of these, and I think that should factor into the formula. My dependent variable is whether the team wins or not. how to do that with multiple independent variables.

The data is arranged as such, there are a list of call types and in another column, there are a list of call lengths. Currently I have a COUNTIF which searches the call type column for certain call types ie BA is off peak but this only tells me how many off peak calls they have made, I need to make it tell me how many minutes of off peak calls there are.
IE this is an example
Call Types Call Lengths (minutes)
BA 1
BA 1
BA 3
BA 2
at the moment my formula would only count this as 4 but I need it to calculate it as 7. This is a very big data set containing around 900 entries per sheet.

I have column E listing all of the favorites and column G the underdogs, each row represents one game, there are 34 all together. I want a formula to pick the team based on a random generation. That part i have....
=choose(randbetween(1,2),e7,g7)
but here is the rub.
I only want the total number of underdogs to be 20% and the favorites to be 80% of all of the picks.
I am not sure it can be done as each formula must look to what the other formulas are doing...aside from it being circular i think it just impossible or i am not as advance as some of you.

I have two factors that both change, resulting in two unique values. I'm trying to determine which portion of the resulting delta is attributable to each factor. Example:
Hourly Cost Run Rate Piece Cost (Hourly Cost / Run Rate)
$105.00 4,500 $0.0233
$126.10 3,000 $0.0420
Two unique results titled Piece Cost = Delta
$0.0420 - $0.0233 = $0.0187
How much of the $0.0187 is attributable to the change in Hourly Cost and how much of the $0.0187 is attributable to the change in Run Rate?

My problem is a little more complex than sumproduct.
I have a ratings column and exposure column. I want to weight those ratings before doing a sumproduct, at the same time ignoring #value.

I'm attempting to sum figures based on the current date. I have a month that's returned from a today function lookup in column B2 (currently 'October').
In F17:Q18, I have the following:
F
April
G
May
H
June
I
July
J
August
[Code] .....
I need to be able to look up today's month (in B2), and sum the row up to that point (so for October, sum Q18:L18). When it ticks into the next month, I want the sum to automatically update to sum to column M
I'm struggling with a SUMIF, my current one sums everything in the row and ignores my "<=B2"
I also tried (MONTH(TODAY()) with corresponding month numbers (Jan 1, Feb 2 etc) in Row 19, but that breaks because Jan-March are 1-3, and it sums them too.
As you can see it's built on a financial year. How to sum the rows up to the current month, and include last year once we're into January-March?

i've attached a file of what i'm working with. only the Data Entry worksheet and Data View worksheet are what i am concerned with
i'm building this billing workbook based on a monthly calendar. i want to have the summary column be a SUM of only the months billed thus far. for example, if the current month is november and i'm entering in billing information for the month of october, how would i be able to show a SUM of only months already billed? in other words, how can i summarize july:september, then see that summary in a column, and then bill october without seeing the effect on the summary column.
currently, the summary column is a summary of all months. i need it to be relative to the Current Date entered in the Data Entry Worksheet.

Using excel 2010: I am calculating a dollar weighting with one isolation factor, the state where the sale took place. My current formula is below. Each dollar amount in AG3:AG2000 has a corresponding weighting in AB3:AB2000. The results are isolated by the corresponding state in the range E3:E2000.
I want to add in an additional isolation, the month when the sale took place. The months are located in H3:H2000. Where in my current formula would I insert the isolation for the month?
=SUMPRODUCT(--(Sales!$E$3:$E$2000='2013 NB'!S8),
Sales!$AG$3:$AG$2000,Sales!$AB$3:$AB$2000)/
SUMIF(Sales!$E$3:$E$2000,'2013 NB'!S8,Sales!$AG$3:$AG$2000)

I have a spread sheet with towns listed in Column G from row 3-81. I months going across row 2 as column labels (they are dates in Jan-14 format). They go from column H-AF.
What I want to happen is to have a formula (not in VBA) which will compare the month in row 2 versus the current month. If it is more than 5 months ago I would like it to return the town in column G for the corresponding row. The only thing I am using to "mark" the last time the town was worked is an X so that is all it needs to look for.

I have historical sales for each month from the last 3 years. I would like to set up a seasonality adjustment for forecasting. I know that it won't be perfect and some may even suggest using regression, but I'd rather not. I'd like to do the following:
In a control sheet, list the months in chronological order beginning in cell A1; January, A2, February; etc., etc. through December.
Next, below each month, I'd like to have a factor. For example, in B1 beneath January, I'd like to be able to plug in 75%. This would say that for each January going forward, that it is 75% of the annual historical average for all periods. Whereas, say in June, it is 140%.
