Good afternoon ,

Assume we have the following dataset :

Good afternoon !

Under R , i developed a custom function that computes the distance between mixed vectors.

The used data is :

I need to run multiple regressions one for every Industry-quarter combination e.g. a regression for financial companies for every single time period e.g. 1999Q3, 1999Q4, 2000Q1, 2000Q2... etc but also utility companies and every retail company, and every food company etc.

I need to run the regression then collect all the coefficients from the regression into a list so then I can append the list back onto the original data frame so that I have the corresponding coefficients.

For example in the data set below, I would want to run the regression Y = x1 + x2 + x3, I have tried using for loops and nested loops and collecting the coefficients into a matrix but I can't seem to get it to work (I am an R novice!)

I have a panel data set that looks a like the following with the firm name, industry, calendar quarters and a few variables:

I have this dropdown menu with checkboxes:

I'm trying to use malloc with a function I wrote in order to grow a list of unique states(no duplicates)

My file contains strings such as;

I am trying to group-by the values in my "value_1" column. But my last column is made up of lists. When I try to group-by using my "value_1" column, the column made up of lists disappears.

Dataframe:

I am trying to join one table from mysql and 2 csv files from hdfs, so as a whole I'm trying to join 3 tables using apache drill.

It works when I join mysql table and 1 dfs file, but fails when I try to join 1 mysql table and 2 dfs csv files. Please help.

Here is the code:

I've looked through the greatest-n-group-by group and can't find this answer and can't make the JOIN solutions work with the WHERE CLAUSE. Here's what I've got.

I'm relatively new to Python world and having trouble with regex.

I'm trying to extract Firm's name before the word 'sale(s)' (or Sale(s)).

I found that Firm's names in my text data are all start with capital letter(and the other parts can be lowercase or uppercase or numbers or '-' or ', for example 'Abc Def' or 'ABC DEF' or just 'ABC' or 'Abc'),

and some of them are taking forms like ('Abc and Def' or 'Abc & Def').

For example,

from the text,

;;;;;PRINCIPAL CUSTOMERS In fiscal 2005, the Company derived approximately 21% ($4,782,852) of its consolidated revenues from continuing operations from direct transactions with Kmart Corporation. Sales of Computer products was good. However, Computer's Parts and Display Segment sale has been decreasing.

I only want to extract 'Computer's Parts and Display Segment'.

So I tried to create a regex
