MP function

MP

Multi-period objects that hold results for group-time average treatment effects

MP(
  group,
  t,
  att,
  V_analytical,
  se,
  c,
  inffunc,
  n = NULL,
  W = NULL,
  Wpval = NULL,
  aggte = NULL,
  alp = 0.05,
  DIDparams = NULL
)

Arguments

• group: which group (defined by period first treated) an group-time average treatment effect is for
• t: which time period a group-time average treatment effect is for
• att: the group-average treatment effect for group group and time period t
• V_analytical: Analytical estimator for the asymptotic variance-covariance matrix for group-time average treatment effects
• se: standard errors for group-time average treatment effects. If bootstrap is set to TRUE, this provides bootstrap-based se.
• c: simultaneous critical value if one is obtaining simultaneous confidence bands. Otherwise it reports the critical value based on pointwise normal approximation.
• inffunc: the influence function for estimating group-time average treatment effects
• n: the number of unique cross-sectional units (unique values of idname)
• W: the Wald statistic for pre-testing the common trends assumption
• Wpval: the p-value of the Wald statistic for pre-testing the common trends assumption
• aggte: an aggregate treatment effects object
• alp: the significance level, default is 0.05
• DIDparams: a DIDparams object. A way to optionally return the parameters of the call to att_gt() or conditional_did_pretest().
