## Usage

 ```1 2``` ```## S3 method for class 'fixest_fitstat' print(x, na.rm = FALSE, ...) ```

## Arguments

 `x` An object resulting from the `fitstat` function. `na.rm` Logical, default is `FALSE`. If `TRUE`, the statistics that are missing are not displayed. `...` Not currently used.

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31``` ```data(trade) gravity = feols(log(Euros) ~ log(dist_km) | Destination + Origin, trade) # Extracting the 'working' number of observations used to compute the pvalues fitstat(gravity, "g", simplify = TRUE) # Some fit statistics fitstat(gravity, ~ rmse + r2 + wald + wf) # You can use them in etable etable(gravity, fitstat = ~ rmse + r2 + wald + wf) # For wald and wf, you could show the pvalue instead: etable(gravity, fitstat = ~ rmse + r2 + wald.p + wf.p) # Now let's display some statistics that are not built-in # => we use fitstat_register to create them # We need: a) type name, b) the function to be applied # c) (optional) an alias fitstat_register("tstand", function(x) tstat(x, se = "stand"), "t-stat (regular)") fitstat_register("thc", function(x) tstat(x, se = "heter"), "t-stat (HC1)") fitstat_register("t1w", function(x) tstat(x, se = "clus"), "t-stat (clustered)") fitstat_register("t2w", function(x) tstat(x, se = "twow"), "t-stat (2-way)") # Now we can use these keywords in fitstat: etable(gravity, fitstat = ~ . + tstand + thc + t1w + t2w) # Note that the custom stats we created are can easily lead # to errors, but that's another story! ```
