Custom Lasso implementation for matrices of indicator functions

lassi(
  x,
  y,
  lambdas = NULL,
  nlambda = 100,
  lambda_min_ratio = 0.01,
  center = FALSE
)

Arguments

x	The covariate matrix
y	The outcome vector
lambdas	A sequence of values for the L1 regularization parameter (lambda) to be used in fitting the LASSO. Defaults to `NULL`.
nlambda	number of lambdas to fit.
lambda_min_ratio	ratio of largest to smallest lambda to fit.
center	...
