For my master's thesis I have to work with a database in order to make a logistic regression model. One of the variables of my model is NEWS, This should be a dummy variable that is equal to 1 if a company had to publish a negative net income (bad news) in a given year, which belongs to the time period of this study (2017, 2018 and 2019), while it still had a positive net income the year before (good news). The dummy is equal to 0 otherwise. Now my professor said that I had to make a dummy that is equal to one when a company had a negative net income during one of the three years, O otherwise. That part I understand. But then she also said that I had to use a LAG function in order to find out if the company had a positive net income the year before the negative net income. And that part I don't understand. I don't really understand how i should do this with the help of SPSS. Below you can find a small part of the data I have to work with.

I have model of Professor and need to "bulk_update". I have to do this in 2 requests from my DB. But i have exception ('QuerySet' object has no attribute 'pk'). If i use get i have another exception(get() returned more than one Professor).

My model.

I have the following code that produces a dot plot:

Dear Stackoverflow community, I am writing this question because I have a problem when plotting an analysis I have performed on a dataset in archaeology. It turns out that I have performed a discriminant analysis by canonical functions, following an example from archaeology professor David L. Carlson, and at the moment of viewing the biplot graph of his data set the graph is shown without problems, where the number of cases associated to the centroids is observed. What happens is that when I plot my data set, the biplot graph I get does not show the number of cases associated with the centroids, I have tried several times but I can not, and I do not know if I have a problem with my data set.

The syntax of the Roman Pottery developed for professor David L. Carlson are shown below:

I'm studying c# from Linkedin Learning, and in a lesson, the professor code worked great in the video, but the exact same file doesn't work for me, returning the error:

Input string was not in a correct format.

This is the code that doesnt work:

I have a theoretical question about the definition of inheritance. I had a test one month ago and we had to give an example for inheritance.

This was my answer:

I have data on fiddler crabs that includes which of its claws are dominate (L or R) (listed as handedness), and the length of specific walking legs (the merus) on each side, which are again sorted by L and R.

What I want is to have a column (or a way) to sort these merus values by whether they were on the same side as the major claw (aka dominate claw). for example, if you go back to the above table, the first crab is right handed, so I would like the Merus_R data to be listed under a column called "Major_merus", and the data from Merus_L to be listed under "Minor_merus". the correct sorting is shown below:

I've already tried the ifelse command recommended by my professor, but I don't know how to use the new data, or why only the Major_merus is correct now.

So for my assignment I have to get the one (given there's one) professor that supervises all the projects in the summer semester 2020. My Idea was to just count the amount of supervising professors. If it's "1" then that professors name gets selected, but if there's 2 or more professors then no one gets selected. But when I test my code, I get 2 different Professors with each having their count on "1"...

Code looks like this

My goal is to grab certain values from database into curated_database, however I am basically stuck at adding multiple items into an object.
