As per our company guidelines we supposed to answer only first question. kindly repost other in next question.
1. The difference between continuous and discrete data sets is as follows,
1) The set of data is said to be continuous if the values belonging to the set can take any values within a finite or infinite interval. And the set of data said to be discrete if the values belonging to the set are distinct and separate.
2) The continuous data is measurable. Continuous data can take on any value as it’s measured. And discrete data is countable. It is typically things counted in whole numbers.
3) Continuous Dataset example: i)Your weight. Your weight can be any weight within the range of human weights. Your weight is not a specific fixed number. ii)Time in a race. A race can be timed to a millisecond.
4)Discrete dataset example: i)Kids per class. How many students there are in each classroom in your school.ii) Apples on a tree. The number of apples on each tree in an orchard. Discrete data can also be categorical, such as green or blue, male or female etc.

What is a standardized regression coefficient?
asked 2022-04-07
We have a situation where we have pairs of points where x=heights of fathers and y=heights of the sons of these fathers. The mean of X is equal to the mean Y and S D ( Y ) = S D ( X ), and 0 < R < 1. Now I am supposed to show that the expected height of a son whose father is shorter than avg. is also less than average, but by a smaller degree. First off I need help understanding the "regression effect" i.e. "Regression Towards the Mean." If the standard deviations are the same why is this happening?

set S of coordinates ( x , y ), and am estimating f ( x ) = a x + b where a > 0. I also happen to know that x , y ( ( x , y ) S y < f ( x ) ).
The question is how I can utilize this knowledge of the upper bound on values to improve the regression result?
My intuition is to run a "normal" linear regression on all coordinates in S giving g ( x ) and then construct g ( x ) = g ( x ) + c, with c being the lowest number such that x , y ( ( x , y ) S y g ( x ) ), e.g. such that g ( x ) lies as high as it can whilst still touching at least point in S. I do, however, have absolutely no idea if this is the best way to do it, nor how to devise an algorithm that does this efficiently.

Contribution of each variable in multiple linear regression
What will be the best measure of the contribution of a variable in multiple linear regression? I was thinking of using the coefficient ratio as a marker of a variable's contribution.
For example:
If the equation is
Y p r e d i c t e d = a 1 X 1 + a 2 X 2 + a 3
Then X 1 's contribution can be written down as:
a 1 a 1 + a 2 + a 3
Is there some other method possible to write down the contribution. Since in this case if any coefficient is negative, there is a possibility that a variable's contribution exceeds 100 %

Correlation of Rolling Two Dice
If A is a random variable responsible for calculating the sum of two independent rolls of a die, and B is the result of calculating the value of first roll minus the value second roll, is is true that A and B have a c o v ( A , B ) 0? In other words, is it true that they are correlated?
I've come to the conclusion that they must be correlated because they are not independent, that is, the event of A can have an impact on event B, but I remain stuck due to the fact that causation does not necessarily imply correlation.
I know that independence −> uncorrelation, but that the opposite isn't true.

What I know, linear means polynomial of degree 1. But then, I found that in one of my lectures, the lecturers are saying that this regression is a linear regression:
Y i = α 0 + α 1 x i + α 2 x i 2
How is this a linear regression when it has quadratic terms in it?
asked 2022-08-08
I need to determine multicollinearity of predictors, but I have only two. So, if VIF 1 1 R j 2 , then in case there are no other predictors VIF will always equal 1? So, maybe it's not even possible to gauge multicollinearity if there are only two predictors?

The Porsche Club of America sponsors driver education events that provide high-performance driving instruction on actual racetracks. Because safety is a primary consideration at such events, many owners elect to install roll bars in their cars. Deegan Industries manufactures two types of roll bars for Porsches. Model DRB is bolted to the car using existing holes in the car's frame. Model DRW is a heavier roll bar that must be welded to the car's frame. Model DRB requires 20 pounds of a special high alloy steel, 40 minutes of manufacturing time, and 60 minutes of assembly time. Model DRW requires 25 pounds of the special high alloy steel, 100 minutes of manufacturing time, and 40 minutes of assembly time. Deegan's steel supplier indicated that at most 40,000 pounds of the high-alloy steel will be available next quarter. In addition, Deegan estimates that 2000 hours of manufacturing time and 1600 hours of assembly time will be available next quarter. The pro?t contributions are $200 per unit for model DRB and $280 per unit for model DRW. The linear programming model for this problem is as follows:
Max 200DRB + 280DRW
s.t.
20DRB + 25DRW 40,000 Steel Available
40DRB + 100DRW ? 120,000 Manufacturing minutes
60DRB + 40DRW ? 96,000 Assembly minutes
DRB, DRW ? 0
