`getRes.CFA.Rd`

get a particular parameter of interest from a cfa object

getRes.CFA(cfaobj, fun, se = T, ...)

cfaobj | a CFA object |
---|---|

fun | a function to apply for every value of the treatment in the cfaobj. The ccfa package provides several built-in functions: E (for expected value as a function of the treatment variable), Var (for the variance as a function of the treatment variable), IQR (the interquantile range as a function of the treatment variable), pov (the fraction of observations with outcomes below some threshold, as a function of the treatment variable), rich (the fraction of observations with outcomes above some threshold, as a function of the treatment variable), but other user-defined functions can be written. The requirement is that they need to take in an ecdf object and output a scalar result. |

se | whether or not to compute standard errors |

... | can pass additional arguments to fun using this argument |
