LpM

LPM is an acronym used in several different fields, and its meaning depends on the context. The most common interpretation is liters per minute, a unit of volumetric flow rate used to quantify the amount of gas or liquid moving through a system each minute. It is widely employed in medical settings to describe oxygen delivery, as well as in industrial ventilation, gas supply, and laboratory measurements.

In econometrics and statistics, LPM stands for the linear probability model. This is a simple approach that uses ordinary least squares to estimate the probability of a binary outcome as a linear function of predictor variables. While easy to estimate, the LPM can produce predicted probabilities outside the interval [0, 1] and may exhibit heteroskedastic errors, limiting its reliability for some applications.

In process mining and data science, LPM can designate a Local Process Model, which refers to a small, reusable fragment of a process extracted from event logs to represent recurring behavior and support analysis of complex workflows.

In manufacturing and electronics packaging, LPM is sometimes used to mean low-pressure molding, a process that uses reduced molding pressure to encapsulate components or form plastics, offering alternatives to higher-pressure techniques in certain applications.

Other uses of the acronym exist in various organizations, projects, or technologies. When encountering LPM, the intended meaning is typically inferred from the surrounding field, documentation, or accompanying units.
