 !!! note
   In some cases levels of repeated effect should not be equal inside each level of subject or model will not have any sense. For example, it is assumed that usually CSH or UN (Unstructured) using with levels of repeated effect is different inside each level of subject.

+    @lmmformula(formula, args...)
+
+Macro for made formula with variance-covariance structure representation. `@lmmformula`
+could be used for shorter `LMM` construction.
+
+Example:
+
+```
+lmm = Metida.LMM(@lmmformula(var~sequence+period+formulation,
+random = formulation|subject:CSH,
+repeated = formulation|subject:DIAG),
+df0)
+```
+
+equal to:
+
+```
+lmm = LMM(@formula(var~sequence+period+formulation), df0;
+random = Metida.VarEffect(@covstr(formulation|subject), CSH),
+repeated = Metida.VarEffect(@covstr(formulation|subject), DIAG),
+)
+```
+
+`@lmmformula` have 3 components - 1'st is a formula for fixed effect, it defined
+like in `StstsModels` (1st argument just provided to `@formula` macro). Other arguments
+should be defined like keywords. `repeated` keyword define repeated effect part,
+`random` define random effect part. You can use several random factors as in example bellow:
+
+```
+lmm = Metida.LMM(Metida.@lmmformula(var~sequence+period+formulation,
+random = formulation|subject:CSH,
+random = 1|subject:DIAG,
+repeated = formulation|subject:DIAG),
+df0)
+```
+
+`random` or `repeated` structure made by template:
+
+`effect formula` | `blocking factor` [/ `nested factor`] [: `covariance structure`]
+
+`|` - devide effect formula form blocking factor definition (necessarily),
+`/` and `:` modificator are optional. `/` work like in MixedModels or in RegressionFormulae -
+expand factor `f|a/b` to `f|a` + `f|a&b`. It can't be used in repeated effect defenition.
+
+`:` - covariance structure defined right after `:` (SI, DIAG, CS, CSH, ets...),
+if `:` not used then SI used for this effect.
+
+Terms like `a+b` or `a*b` shuould not be used as a blocking factors.
