QUESTION
I've these two tables t1
and t2
stored an a database MySql version 8.0.17
It's important to say that the table t2
can contain thousands of rows with different unit code (field sUn
)...
Instead the table t1
contains only the how and code of each unit (field TABLE_NAME
)
ANSWER
Answered 2021-Apr-09 at 13:36In MySQL, sad to say, pivoting is hard to do for a mess of arbitrarily named columns.
This gets the result you want (dbfiddle on db-fiddle.com, which offers MySQL 8.)
QUESTION
I'm using ols
in statsmodels
to run a regression. Once I run the regressions on each row of my dataframe, I want to retrieve the X variables from patsy
thats used in those regressions. But, I get an error that I just cant seem to understand.
Edit: I am trying to run a regression as presented in the answer here, but want to run the regression across each row of a grouped version of my dataframe df
, where it is grouped by Date
,bal
, dist
, pay_hist
, inc
, bckts
. So I first group this data as described above and then try to run the regression on each row where df
is grouped by Date
: df.groupby(['Date']).apply(ols_coef,'bal ~ C(dist) + C(pay_hist) + C(inc) + C(bckts)')
My code is as follows:
...ANSWER
Answered 2020-Oct-24 at 06:48The problem is that you're passing a grouped dataframe into thepasty.dmatrices
function. Since the grouped dataframe is iterable, you can do it in a loop like this, and store all of your X dataframs (one for each group) into a dictionary:

I am trying to get every item name from the steam community market (I market where you buy and sell virtual items, which you can use in games).
Steam has an API link for this, it says "total_count":15227
, which represents the number of Items.
But when I try to download it, I get only 100 items. Why is that so?
This is how I download it:
ANSWER
Answered 2020-Aug-09 at 19:34If you look at the response you can see the "pageSize" parameter that has the value 100.
Apparently 100 is the maximum page size the steam api returns.
QUESTION
In the past few days I have been trying to find how to do Fama Macbeth regressions in R. It is advised to use the plm package with pmg, however every attempt i do returns me that I have an insufficient number of time periods.
My Dataset consists of 2828419 observations with 13 columns of variables of which I am looking to do multiple cross-sectional regressions. My firms are specified by seriesis, I have got a variable date and want to do the following Fama Macbeth regressions:
...ANSWER
Answered 2019-Aug-08 at 22:14This is almost certainly due to having NAs in the variables in your formula. The error message is not very helpful - it is probably not a case of "too few time periods to estimate" and very likely a case of "there are firm/unit IDs that are not represented across all time periods" due to missing data being dropped.
You have two options - impute the missing data or drop observations with missing data (the latter being a quick test that the model works without missing points before deciding what you want to do that is valid for estimtation).
If the missingness in your data is truly random, you might be okay just dropping observations with missingness. Otherwise you should probably impute. A common strategy here is to impute multiple times - at least 5 - and then estimate for each of those 5 resulting data sets and average the effect together. Amelia
or mice
are very strong imputation packages. I like Amelia
because with one call you can impute n
times for that many resulting data sets and it's easy to pass in a set of variables to not impute (e.g., id variable or time period) with the idvars
parameter.
EDIT: I dug into the source code to see where the error was triggered and here is what the issue is - again likely caused by missing data, but it does interact with your degrees of freedom:

QUESTION
I started replicating the value factor used by Fama and French in r to build a portfolio strategy for my final dissertation.
I have a dataset of monthly market caps from the S&P 500 over the years. I created a loop to determine whether the variable (mkt cap) of a determined observation at a certain date is higher or lower than a certain threshold computed cross-sectionally at the same time (across all the observations of the variable mkt cap at time t). To achieve this, I thought the appropriate technique to be a for loop. In this way for each date I calculate the threshold and check the criteria. Unfortunately I am not able to store the logical during the loop. When I print the results I can see what I would like to store but when I try to store I get only the results related to the last step of the loop.
...ANSWER
Answered 2020-Apr-01 at 15:15You won't need a loop.
Assuming your dataframe is data_tbk
, this code will create new variable is_higher
. 1 if mktcap
more then Q80%, 0 if less than Q20%, and NA for the rest.

QUESTION
In my table, the lines are form: 97.5%, 10/30, 41 RPM, 3.6 seconds, $4750, $100
If I set the type data-type = "number"
in the rows everything is removed except for the numbers, but I need to be output completely as I wrote in the example.
How can I do what sorted by numeric values only? I think it can be realise through the JS, but I do not know it.
Regarding the second line, I want to be sorted by numbers before the character "/"
ANSWER
Answered 2019-Jun-17 at 07:13You can use data-sort-value
data attribute to manually set the value for sorting.
From Footable Sorting Doc
Cell options
sortValue : The value used by the component to perform sorting operations. To supply this option through data attributes you must specify the attribute on the td element.
You can achieve this by either directly using data-sort-value
inside a td
or you can use javascript
