At first I get data from websocket connection and parse it to put in my state.

I have a dataset (Panel data) of the Dow Jones' stocks with daily data (named 'data'):

I have a list object with components that look like the following:

I want to create several pandas dataframes with names are unique values in a column of orginal pandas dataframe. For example: given orginal dataframe as in the picture:

I would like to create new dataframes for every ticker from this orginal dataframe. Here I have:

I need some help understanding how the verification of a transaction works in Corda. If I understood correctly, all parties in a transaction are responsible for verifying it themselves.

I have a use case very similar to the negotiation cordapp between 2 parties. When writing a flow, I verify the unsigned transaction in the initiator:

I am trying to construct a covariance matrix that I believe has to be done using a loop.

I have a set of 30 regressions against a single index (DowJones) that creates a table with intercepts (alpha), slopes (beta_i), and standard deviation of residuals (epsilon). I specifically need to construct the matrix σij = βi* βj* σ^2m where βi, βj, etc are the slopes from this table and σ^2m is the variance variable called dji_var . So first slope * first slope * dji_var populates the first element of the covariance matrix.

Does anyone have a loop that can do this easily for me? The dimensions of my covariance matrix should be 30x30.

Thank you

This is what I have so far:

I am having a problem with coding. I used excel VBA to extract data from a webpage to excel. The webpage is https://proptx.midland.com.hk/utx/index.jsp?est_id=E12837&lang=en Click "All transaction" and it displays a second table at the bottom of the first table. I would like to extract data from the bottom table (not the top one).

Here is the code:

Is this possible to take that values from console: and save them into java list/map?

I printed that logs in that way:

I want to enter data from a form to a database using netbeans and java DB. My problem is that I cant figure out how to pass the data that the user enters in the form to the database.

I have tried creating an entity class and connect it through that but based on the guide that I am following I end up having access to the entire database rather than just the form

EDIT:This is a school project and I haven't been taught JDBC, at least yet.
