about metis

An open desktop environment for serious PLS-SEM work

metis is a free desktop application for researchers and students who need a serious PLS-SEM workflow without expensive licences. It combines a visual modelling canvas with the R and seminr analysis engine so you can move from theory to interpretable results in one place.

visual model design

Build constructs and structural paths on an interactive canvas, then keep coefficients and model outputs connected to the diagram that produced them.

complete PLS-SEM workflow

Run PLS-SEM, bootstrap, and PLS predict workflows with practical control over subsamples, weighting schemes, and iterations.

no-code analysis workflow

Use seminr-powered statistics without writing R code. metis handles the backend pipeline while you stay focused on theory and interpretation.

private local computation

Your dataset and calculations stay on your machine. metis runs the analysis engine locally, with no cloud upload requirement.

canvas

Keep the model and the results in view

Move from the canvas to coefficients and back without losing context.

metis keeps path coefficients, loadings, and fit indices close to the model that produced them, so the structure and the interpretation stay aligned.

data

Work with real datasets from the start

Build with your files, not placeholder examples.

Import your dataset and design with real indicator names, real loadings, and real significance values from the first run onward.

zero-code

No R required

Let the statistical engine run in the background while you stay with the research.

metis handles bootstrapping, PLS predict, NCA, cIPMA, IPMA, and the seminr setup work for you, so you can focus on specification, interpretation, and reporting.

100% local processing

Your data never leaves your machine.

The R engine runs on localhost only. No account required, no telemetry, no cloud. Your research data stays yours.
