Conditional Logit

Modern · Tercih

Conditional Logit is one of the statistical analyses applied automatically in MerQur. This page illustrates — on a Architecture, Planning & Design sample dataset — how the analysis is run, what the MerQur output looks like, and how the result is reported in APA 7 format.

🎯 What is it for?

Conditional Logit automatically performs all required assumption checks (normality, homogeneity of variance, etc.) for the relevant data type in the background and presents the results with a clear table + chart. Automatic interpretation to the APA 7 standard, effect sizes such as Cohen’s d/η²/R², and 95% confidence intervals are reported.

📌 When is it used?

  • Statistical analysis of measurements in the Architecture, Planning & Design domain
  • To produce APA 7-compatible result tables for academic publications
  • Hypothesis testing and decision-making processes
  • Undergraduate / master’s / PhD theses after the appropriate method has been selected

📐 Assumptions

  • Appropriate scale — Variables must be at the measurement level required by the analysis (nominal/ordinal/interval/ratio)
  • Independent observations — Observations must come from individuals independent of one another
  • Sufficient sample size — The minimum n requirement for the analysis must be met
  • Outlier check — Outliers must be detected and evaluated

If assumptions are violated, MerQur automatically suggests a non-parametric or robust alternative.

📊 Sample Dataset — Architecture, Planning & Design

ℹ Note: The scenario, MerQur output and interpretation below were produced by actually running the real example dataset in MerQur. Numeric results on your own data will differ; the goal is to show how the analysis is set up and interpreted end-to-end.

🎬 Example File

This analysis is demonstrated on the following example dataset for Architecture, Planning & Design:

Peyzaj_Mimarligi/85_conditional_logit_transport.xlsx

🎬 Scenario

We model which transport mode users take to the park (discrete choice) from duration and cost; conditional logit is appropriate.

⚙️ Variable Selection

  • Chooser: participant_id | Chosen: chosen | Predictors: duration_min, cost_TL

📈 MerQur Output

CONDITIONAL LOGIT RESULT ───────────────────────────────────────────── Pseudo R2 (McFadden) = 0.803 (very high) Transport-mode choice ~ duration (min) + cost (TL)

💬 Interpretation

We examined which transport mode (walking, bicycle, public transport, car) users take to the park with a conditional logit model — each user selects one from a choice set. McFadden pseudo R2 = 0.80 is very high (0.2-0.4 is already strong for choice models): duration and cost explain the mode choice almost completely. The model shows users prefer shorter, lower-cost modes. This method is the basis of transport and accessibility analysis; in landscape it is powerful for modelling access modes to parks and policies promoting green/active travel (walking, cycling).

⚠ Common Mistakes

  • Misidentifying the data type (e.g., loading a categorical variable as numeric)
  • Skipping assumption checks and going straight to the p-value
  • Failing to report effect size — APA 7 requires both p and effect size
  • Failing to apply a Type I error correction (Bonferroni/Tukey) in multiple comparisons
  • Not switching to a non-parametric alternative when n is insufficient
