Which of the following statements about the Lasso are true with respect to the OLS​ estimates?

Mathematics
1 answer:
mash [69]4 years ago
8 0

Answer:

B and C

Step-by-step explanation:

B - The purpose of LASSO is to shrink parameter estimates towards zero, lasso shrinkage causes the estimates of the non-zero coefficients to be biased towards zero.

C- Lasso shrinks more accurately than the ridge. In the case of multiple coefficients Lasso selects only some some features and reduces the coefficients of the others to zero. This is called feature selection and it's not a possible in the ridge.

What is 2/7 ÷ 4/21 fully reduced
NikAS [45]
When dividing fractions, you flip the second fraction and multiply

\dfrac{2}{7} \div \dfrac{4}{21}~becomes~\dfrac{2}{7}*\dfrac{21}{4}

Next, we multiply:

\dfrac{2}{7}*\dfrac{21}{4}=\dfrac{42}{28} = \dfrac{21}{14}= 1 \dfrac{1}{2}

What should be added to -5/4 to get -1?
nikitadnepr [17]

Answer: 1/4

Step-by-step explanation:

We can actually write an equation to find what should be added to get -1.

-\frac{5}{4}+x=-1

We get this equaiton because the problem asks what should be added to -5/4 to get -1. We put x in place to see what number fits. X is being added to the -5/4.

x=-1+\frac{5}{4}

x=-\frac{4}{4}+\frac{5}{4}

x=\frac{1}{4}

PLEASE PLEASE PLEASEE UGENT I don’t know how to solve these questions
MrRa [10]

Answer:

Step-by-step explanation:

1). In ΔTPW and ΔGHD,

  Triangles will be congruent by the properties of congruence,

  1). SSS - (Sides - Side - Side) property of congruence

  2). SAS - (Side - Angle - Side) property of congruence

  3). ASA - (Angle - Side - Angle) property of congruence

2). ΔABE ≅ ΔMNP

   ∠A ≅ ∠M

   ∠B ≅ ∠N

   ∠E ≅ ∠P

   Side AB ≅ Side MN

   Side AE ≅ Side MP

   Side BE ≅ Side NP

   Another way to write the congruency statement → ΔAEB ≅ ΔMPN

3). ΔQRY ≅ ΔJLS

   ∠Q ≅ ∠J

   ∠R ≅ ∠L

   ∠Y ≅ ∠S

   Side QR ≅ Side JL

   Side RY ≅ Side LS

   Side QY ≅ Side JS

   Anthe way to write the congruency statement → ΔQYR ≅ ΔJSL
