QUESTION

Logistic regression - create new variable using others (SAS)

Asked 2021-Jun-15 at 16:41

I have a small dataset based on a survey(about 80 obsv) & on which i want to perform a logistic regression using SAS.

My survey contains some variables (named X1,X2,X3) that i want to reunite as categories of a new created variable named X4.

The problem is that those variables X1-X3 already have categories (YES/NO/WITHOUT OPINION)

How can i reunite them as categories of X4 but with considering the values that they have ?

to help you understand my question :

Y(=1/0) = X1 X2 X3

X1-X3 each have 3 categories (YES/NO/WITHOUT OPINION)

What i want is :

Proc logistic data = have ; model Y = X4 and others such as age, city... but X4 can take 3 values.

The problem isn't creating X4 based on X1-X3 but how to affect X4 the values that X1-X3 each takes ?

(NB: i say X1-X3 but it's more)

I do this in SAS but even a theorical explanation would be helpful !

Thank you.

I think that the comments are right for the most part - this probably won't help your regression.

But - to answer how to literally do this; usually what you would do is to use powers of 2 (or 3).

So, for typical "yes/no" where you don't care about the 3rd one, you'd assign things like this:

Crash on a protocol witness related issue

Asked 2021-Jun-15 at 13:26

In my iOS app "Progression" there is rarely a crash (1 crash in ~1000+ Sessions) I am currently not able to fix. The message is

Progression: protocol witness for TrainingSetSessionManager.update(object:weight:reps:) in conformance TrainingSetSessionDataManager + 40

This crash points me to the following method:

Answered 2021-Jun-15 at 13:26

While editing my initial question to add more context as Jay proposed I think it found the issue.

What probably happens? The view where the crash is, contains a table view. Each cell will be configured before being presented. I use a flag which holds the information, if the amount of weight for this cell (it is a strength workout app) has been initially set or is a change. When prepareForReuse is being called, this flag has not been reset. And that now means scrolling through the table view triggers a DB write for each reused cell, that leads to unnecessary writes to the db. Unnecessary, because the exact same number is already saved in the db.

My speculation: Scrolling fast could maybe lead to a race condition (I have read something about that issue with realm) and that maybe causes this weird crash, because there are multiple single writes initiated in a short time.

Solution: I now reset the flag on prepareForReuse to its initial value to prevent this misbehaviour.

The crash only happens when the cell is set up and the described behaviour happens. Therefor I'm quite confident I fixed the issue finally. Let's see. -- I was not able to reproduce the issue, but it also only happens pretty rare.

QUESTION

Is there a way to perform arithmetic on integer which has been converted from a string cpp

Asked 2021-Jun-15 at 13:14

So basically I am getting two string inputs in the form of coordinates as (x,y) and then I am adding the numbers from the inputted string (which are p1 and p2) to different variables and then adding those variables (which are x1,x2,y1,y2). So is there a way to add the variables together i.e perform arithmetic on the variables, (not concatenate)

ANSWER

Answered 2021-Jun-15 at 13:14

You can do this with std::stoi(). Add a line to put these strings into int variables and do your arithmetic:

int x = stoi(x1);

What is the reset type of the reset signal of an always_latch .?

Asked 2021-Jun-15 at 06:39

I don't have much knowledge on system verilog and I have the following question.

As I know, if an edge of a reset signal has been triggered in the sensitivity list of an always block then the reset type of that reset signal is 'asynchronous' I need to know, what is the reset type of the reset signal of an always_latch?

...

ANSWER

Answered 2021-Jun-15 at 06:39

Both resets are asynchronous. You cannot have a synchronous reset in a latch because there is no clock. The always_latch construct in your example creates an implicit sensitivity list

How to change the line style of ECharts custom graph from solid to dashed or dotted

Asked 2021-Jun-14 at 11:10

I created a custom graph using Apache ECharts to draw a vertical line from the input data. Following ECharts documentation and some online examples, I was able to draw the line and custom it with color or width as per the MWE below.

My question is how to configure the line style as dotted or dashed. I searched extensively but could not find any options or documentation on that.

...

ANSWER

Answered 2021-Jun-14 at 11:10

You can easily make custom dashed line in echarts. You need to pass lineDash to the graphic element object.

lineDash is stroke-dasharray attribute of line defining the pattern of dashes and gaps. Pass the values of dashes and gaps in form of an number array.

Set after value for DIV dynamically

Asked 2021-Jun-14 at 10:06

I have a div container that will layout each item evenly for the full width of the screen.

I would like to adjust the BACK div behind the selected input dynamically. I know in theory how to do it: do a transform: translate to #after of the BACK div. But I have no idea how to calculate the correct px value, depending on what input tag has been selected.

The codepen to view this is available here: https://codepen.io/depechie/pen/oNZagLa

The desired end result visually should be like following picture. So the BACK div ( the blue outline ) should be placed behind the selected input.
