Calculate the average recurrence interval for a specific number; based on a condition

[D_Spark]

Hi,

Assuming I put my chosen value, e.g. 1, in B1:
Im currently using the following formula
=MMULT(AGGREGATE({14,15},6,ROW(A1:A1000)/(A1:A1000=B1),1),{1;-1})/(COUNTIF(A1:A1000,B1)-1)

I want to introduce a condition so for the above to work only when across A values where the values in (C1;C1000) equal 1

Hi

A:A=B1 and C:C=1 are similar conditions.
I'd say you just duplicate what you did for the first condition.

=MMULT(AGGREGATE({14,15},6,ROW(A1:A1000)/(A1:A1000=B1)/(C1:C1000=1),1),{1;-1})/(COUNTIFS(A1:A1000,B1,C1:C1000,1)-1)

Sorry I dont think I explain this very well.

Column C
This is numeric field where each column cell is either 1......or 2........ or......3

Column A values vary from a minimum of 1 to a maximum of 100

there arent unique

Can you post an example ?
(not the 1000 rows, just 7-8 )

If you don't know how to post a table, post just lines of text with values separated by commas.

Re: Help needed to calculate the average recurrence interval for a specific number; based on a condition

A1=10..................... c1=0
A2=5....................... c2=1
A3=10..................... c3=1
A4=1....................... c4=0
A5=4...................... c5=0
A6=10.................... c6=0
A7=10..................... c7=1
A8=6...................... c8=0
A9=10..................... c9=0
A10=10................... c10=1


b1=10

So I want it to work out the average recurrence of b1, i.e. 10 but only when the c value is 1

This means for the above:
Row 3 to Row 7 is a delay of 4 rows
Row 7 to Row 10 is a delay of 3 rows

Therefore average = (4+3)/2 = 3.5

Hi

My formula works OK with the example you posted.

In F1:

=MMULT(AGGREGATE({14,15},6,ROW(A1:A1000)/(A1:A1000=B1)/(C1:C1000=1),1),{1;-1})/(COUNTIFS(A1:A1000,B1,C1:C1000,1)-1)

Can you post an example where my formula does not work so that I can test?
