Below, we fit a quantile regression of miles per gallon vs. car weight:Yet, what has long been heeded when modeling the probability of binary outcomes with the widespread use of logistic and probit regression, so far appears to have been overlooked with continuous bounded outcomes with consequences at times disastrous. Logistic quantile regression constitutes an effective method to fill this gap.5.3 Fitting a model. Logistic regression is a special case of a broader class of generalized linear models, often known as GLMs. Specifying a logistic regression model is very similar to specify a regression model, with two important differences: We use the glm () function instead of lm () We specify the family argument and set it to binomial. Value. dlogis gives the density, plogis gives the distribution function, qlogis gives the quantile function, and rlogis generates random deviates.. The length of the result is determined by n for rlogis, and is the maximum of the lengths of the numerical arguments for the other functions.. The numerical arguments other than n are recycled to the length of the result.To fill this research gap, we used quantile regression models to assess the effect of greenspace that might vary across the distribution of lung function parameters measured by spirometry. Quantile regression models have already provided new insights in pulmonary function research (Bottai et al., 2011; Zhang et al., 2015).Quantile regression generalizes the concept of a univariate quantile to a conditional quantile given one or more covariates.
