print.savvyPR: Print a Parity Regression Model Object

In savvyPR: Savvy Parity Regression Model Estimation with 'savvyPR'

Print a Parity Regression Model Object

Description

Prints a summarized output of a fitted parity regression model object. It clearly displays the model's configuration and the resulting estimated coefficients.

Usage

## S3 method for class 'savvyPR'
print(x, digits = max(3, getOption("digits") - 3), ...)

Arguments

x	A fitted model object of class "savvyPR" returned by savvyPR.
digits	Significant digits to be used in the printout.
...	Additional arguments passed to the generic print function.

Details

Print a Parity Regression Model Object

This function is an S3 method for the generic print function. It formats and prints the matched call that produced the savvyPR object, followed by a summary data frame. This summary includes:

• The parameterization method used ("budget" or "target").

• The number of non-zero coefficients.

• Whether an intercept was included.

• The penalty value (lambda), if any was applied.

Finally, it prints a data frame of the estimated coefficients.

Value

Invisibly returns a data frame summarizing the model, including the parameterization method, number of non-zero coefficients, intercept status, and lambda value.

Examples

# Generate synthetic data
set.seed(123)
n <- 100
p <- 10
x <- matrix(rnorm(n * p), n, p)
beta <- matrix(rnorm(p), p, 1)
y <- x %*% beta + rnorm(n, sd = 0.5)

# Fit and print a Budget-based model
fit_budget <- savvyPR(x, y, method = "budget", val = 0.05)
print(fit_budget)

# Fit and print a Target-based model
fit_target <- savvyPR(x, y, method = "target", val = 1)
print(fit_target)
