Use the following cell phone airport data speeds (Mbps) from a particular network. Find P10. 0.1 0.1 0.3 0.3 0.3 0.4 0.4 0.4 0.

Answer:

$P_{10} =0.1$

Explanation:

Given

$0.1, 0.1, 0.3, 0.3, 0.3, 0.4, 0.4, 0.4, 0.6, 0.7, 0.7, 0.7, 0.8, 0.8$

Required

Determine $P_{10}$

$P_{10}$ implies 10th percentile and this is calculated as thus

$P_{10} = \frac{10(n+1)}{100}$

Where n is the number of data; n = 14

$P_{10} = \frac{10(n+1)}{100}$

Substitute 14 for n

$P_{10} = \frac{10(14+1)}{100}$

$P_{10} = \frac{10(15)}{100}$

Open the bracket

$P_{10} = \frac{10 * 15}{100}$

$P_{10} = \frac{150}{100}$

$P_{10} = 1.5th\ item$

This means that the 1.5th item is $P_{10}$

And this falls between the 1st and 2nd item and is calculated as thus;

$P_{10} = 1.5th\ item$

Express 1.5 as 1 + 0.5

$P_{10} = (1 +0.5)\ th\ item$

$P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item$

From the given data; $1st\ item = 0.1$ and $2nd\ item = 0.1$

$P_{10} = 1^{st}\ item +0.5(2^{nd} - 1^{st}) item$ becomes

$P_{10} =0.1 +0.5(0.1 - 0.1)$

$P_{10} =0.1 +0.5(0)$

$P_{10} =0.1 +0$

$P_{10} =0.1$

What is unique about the TODAY and NOW functions?

Degger [83]

Answer:

The formula does not require arguments.

Explanation:

One of the programs or software that runs on a computer is Microsoft Office programs. One of these programs is called Microsoft Excel. It is a spreadsheet program where calculations can be made, graphs, diagrams can be plotted and drawn as well.

In other to utilize Microsoft Excel properly, we make use of what we call FUNCTIONS. Functions in Microsoft Excel are defined as formulas, that have already been prepared or created before hand in the Microsoft Excel program so that we can be able to used Microsoft Excel properly and efficiently. Functions may or may not require ARGUMENTS to carry out necessary calculations.

An ARGUMENT is a number or variable that functions require to carry out or do their calculations.

Examples of the functions found in Microsoft Excel are the TODAY and NOW functions. These two functions are used in spreadsheets on Microsoft Excel with regards to Date and Time.

TODAY function is used to give us or update the current or present date while the NOW function gives us or updated the current date and time.

The uniqueness or similarities between the TODAY and NOW functions is that their formula do not require arguments.

8.11 LAB: Count characters - functions Write a program whose input is a character and a string, and whose output indicates the n

Shkiper50 [21]

Answer:

#include<iostream>

using namespace std;

int CountCharacters(char userChar, const string inputstr){

int k = 0;

int iter = 0;

for (iter = 0; iter < inputstr.size(); iter++){

if (inputstr[iter] == userChar){

++k; }}

return k;}

int main(){

string str;

char userChar[1];

cout<<"Char: "; cin>>userChar;

cin.ignore();

cout<<"String: "; getline(cin, str);

cout<<CountCharacters(userChar[0],str);

return 0;}

Explanation:

Written in C++:

The function is defined here:

int CountCharacters(char userChar, const string inputstr){

This initializes a count variable k to 0

int k = 0;

This initializes an iterating variable iter to 0

int iter = 0;

This iterates through the characters of the string being passed to the function

for (iter = 0; iter < inputstr.size(); iter++){

This checks for matching characters

if (inputstr[iter] == userChar){

If found, k is incremented by 1

++k; }}

This returns the total count

return k;}

The main begins here

int main(){

This declares a string variable

string str;

This declares a character variable

char userChar[1];

This gets input for the character variable

cout<<"Char: "; cin>>userChar;

This lets the user get another input

cin.ignore();

This gets input for the string variable

cout<<"String: "; getline(cin, str);

This calls the function and return the count of character in the string

cout<<CountCharacters(userChar[0],str);

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)
