# Generate lambda sequence.

`setup_lambda.Rd`

Generate lambda sequence.

## Arguments

- X
Input matrix, of dimension

`nobs`

x`nvars`

; each row is an observation vector.- y
Response variable, of length

`nobs`

. For`family="gaussian"`

, it should be quantitative; for`family="binomial"`

, it should be either a factor with two levels or a binary vector.- weights
Observation weights.

- lambda.min.ratio
The smallest value for

`lambda`

, as a fraction of`lambda.max`

, the smallest value for which all coefficients are zero. The default depends on the sample size`nobs`

relative to the number of variables`nvars`

.- nlambda
The number of

`lambda`

values.
