fit() Parametersįorce_orthogonal ( bool) – whether factors in the model should be recoded using polynomial contrasts to ensure valid type-3 SS calculations. Note that this will overwrite factors specified in the last call to. However, the force_orthogonal flag can refit the regression model with orthogonal polynomial contrasts automatically guaranteeing valid SS type 3 inferences. Like R, this method does not ensure that contrasts are orthogonal to ensure correct type-3 SS computation. Return a type-3 ANOVA table from a fitted model. Model_obj ( lmer model) – rpy2 lmer model objectįactors ( dict) – factors used to fit the model if anyĪnova ( force_orthogonal = False ) ¶ Residuals ( numpy.ndarray) – model residualsįits ( numpy.ndarray) – model fits/predictions Ranef_corr ( pd.DataFrame) – random effects correlations Ranef_var ( pd.DataFrame) – random effects variances subjects and items)Ĭoefs ( /list) – model summary table of population parameters subjects and items)įixef ( pd.DataFrame/list) – cluster-level parameters returns list if multiple cluster variables are used to specify random effects (e.g. difference between coefs and fixefs returns list if multiple cluster variables are used to specify random effects (e.g. Ranef ( pd.DataFrame/list) – cluster-level differences from population parameters, i.e. Warnings ( list) – warnings output from R or Python Grps ( dict) – groups and number of observations per groups recognized by lmerĭesign_matrix ( pd.DataFrame) – model design matrix determined by lmerĪIC ( float) – model akaike information criterion

Parametersįormula ( str) – Complete lmer-style model formulaĭata ( ) – input dataįamily ( string) – what distribution family (i.e.) link function to use for the generalized model default is gaussian (linear model)įitted ( bool) – whether model has been fitĭata ( pd.DataFrame) – model copy of input data Most attributes will not be computed until the fit method is called. This class stores as much information as it can about a merMod object computed using lmer and lmerTest in R. Model class to hold data outputted from fitting lmer in R and converting to Python object. Lmer ( formula, data, family = 'gaussian' ) ¶ Model class for estimating lme4 multi-level models in python class pymer4.models.
