# static_glm

##### Function to make a static glm fit

Function to make a static glm fit

##### Usage

```
static_glm(formula, data, by, max_T, ..., id, family = "logit", model = F,
weights, risk_obj = NULL, speedglm = F, only_coef = FALSE, mf)
```

##### Arguments

- formula
`coxph`

like formula with`Surv(tstart, tstop, event)`

on the left hand site of`~`

- data
Data frame or environment containing the outcome and co-variates

- by
Length of each intervals that cases are binned into

- max_T
The end time of the last bin

- ...
arguments passed to

`glm`

or`speedglm`

. If`only_coef = TRUE`

then the arguments are passed to`glm.control`

if`glm`

is used- id
The id for each row in

`data`

. This is important when variables are time varying- family
`"logit"`

or`"exponential"`

for the static equivalent model of`ddhazard`

- model
`TRUE`

if you want to save the design matrix used in`glm`

- weights
weights if a skewed sample or similar is used

- risk_obj
A pre-computed result from a

`get_risk_obj`

. Will be used to skip some computations- speedglm
`TRUE`

if`speedglm`

should be used.- only_coef
`TRUE`

if only coefficients should be returned. This will only call the`speedglm.wfit`

or`glm.fit`

which will be faster.- mf
model frame for regression. Needed when

`only_coef = TRUE`

##### Details

Method to fit a static model corresponding to a `ddhazard`

fit. The method uses weights to ease the memory requirements. See `get_survival_case_weights_and_data`

for details on weights

##### Value

The returned list from the `glm`

call or just coefficients depending on the value of `only_coef`
