Cumulative Sum without Script

For this question, I’ve created a Google Apps Script function, that calculates the cumulative sum of a range. Martin Hawksey on Google+ made a comment about a more efficient way of calculating the cumulative sum:

function cumulativeSum(array){   var output = [];   for (i in array){     if(i==0) {       if (array[i].length > 1) throw ("Only single column of data");       output.push([array[i][0]]);     } else {       output.push([output[i-1][0] + array[i][0]]);     }   }   return output; } 

My question is: can this be achieved with the usage of formula’s?

Does latest SharePoint 2013 Cumulative update really include all previous Cumulative updates?

When a cumulative update is published, it is supposed to contain all the previous cumulative updates.

KB 4022236 size is 290.0 MB (August 14, 2018)

KB 4092472 size is 77.7 MB (December 11, 2018) on download center and 3.7 MB (???) on windows update

Is the newest cumulative update downloading all the old ones in background? That would explain why the size is not reflecting the previous ones size.

IS the new SharePoint 2013 Cumulative updates include all previous Cumulative updates and Service packs?

Hi the new SharePoint 2013 Cumulative updates include all previous Cumulative updates and Service packs because in my farm when I join the new server I am facing issues, when I install March 12, 2019, cumulative update for SharePoint Enterprise Server 2013 (KB4462219) and run the Configuration wizard it showing missing locally below service pack 1.

Service Pack 1 for Microsoft SharePoint Server 2013 (KB2880552)

IS March Security upates for sharepoint 2013 included in March 12, 2019, cumulative update for SharePoint Enterprise Server 2013 (KB4462219)?

Here I want to fix the CVE-2019-0604 | Microsoft SharePoint Remote Code Execution Vulnerability in my SharePoint 2013 farm.

Are skill modifiers cumulative (even beyond plus/minus 30%)?

I haven’t GMed Warhammer FRP 2nd edition for quite a while and my knowledge’s gone a bit rusty, I’m afraid.

Are skill modifiers cumulative (even beyond plus/minus 30%) in WFRP 2nd edition?

I tried to find the answer in the core book, but all I found was that skill difficulty modifiers are mostly up to the GM, and that they very rarely exceed +/- 30%. Is that correct, or have I missed something?

For example, Hans is about to parry with his off-hand weapon, which gives him a -20% (as it’s not defensive and he’s not ambidexterous), and it’s pouring at night, in a back alley, which I’d say is also a -20% (because it’s slippery and dark and Hans can’t see much.) Does he roll with -40%, or does it stop at -30% (as all these things make it a “Very Hard” roll which means -30%)?

User rank based on cumulative rows

Table structure (some fields are hidden):

+---------+---------+------------+-------------+-------+-------+ | user_id | kind_id | country_id | province_id | value | score | +---------+---------+------------+-------------+-------+-------+ |       1 |     201 |          1 |           1 |     1 |     5 | |       1 |     102 |          1 |           1 |    31 |   155 | |       1 |     201 |          1 |           1 |     6 |    30 | |       1 |     109 |          1 |           1 |    33 |   165 | |       2 |     202 |          1 |           4 |    76 |   380 | |       2 |     201 |          1 |           4 |     5 |    25 | |       2 |     209 |          1 |           4 |     9 |    45 | |       2 |     302 |          1 |           4 |     8 |    40 | |       2 |     201 |          1 |           4 |    14 |    70 | |       3 |     201 |          1 |           9 |     7 |    35 | |       3 |     201 |          1 |           9 |     9 |    45 | |       3 |     201 |          1 |           9 |     2 |    10 | |       3 |     201 |          1 |           9 |     5 |    25 | |       3 |     201 |          1 |           9 |     7 |    35 | |     ... |     ... |        ... |         ... |   ... |   ... | +---------+---------+------------+-------------+-------+-------+ 

Rank is calculated based on sum of score of user’s activities. I saw many questions here and on Stackoverflow but my problem is more complex.

I need 3 rank values per user: global, country (for users in same country), province (same as country). For example a rank value for user 1 may be like this {"global": 9, "country": 3, "province": 1}. I do not need rank of all users but for one individual user.

I tried a dozen queries but can’t calculate this three with one query. or, at least, three clean and efficient queries.

I will cache the result for some time, but still efficiency is important since the activities table contains many records and will grow as time passes.

How can I do this?

Thanks.

Cumulative sum of a dataframe column with restart

I would like to perform the following function on a dataframe.

Calculate the cumulative sum of a column, notice:

  1. It looks at the previous index only, not including the current one, e.g. the very first one will be zero as there is no previous data to look at.

  2. When it doesn’t cumulate, e.g the increment is zero, it restarts the count.

          Number  Cumulative    0       1           0    1       1           1    2       1           2    3       0           3    4       0           0    5       1           0    6       1           1    7       0           2 

I know there is an expanding function, but it doesnt restart when it sees zero
