This fitting can be done using the survfit function of the survminer library. The visual representation of this function is usually called the Kaplan-Meier curve, and it shows what the probability of an event (for example, survival) is at a certain time interval. Kaplan-Meier is a statistical method used in the analysis of time to event data. The Kaplan Meier plotter is capable to assess the effect of 54k genes (mRNA, miRNA, protein) on survival in 21 cancer types including breast (n=6,234), ovarian (n=2,190), lung (n=3,452), and gastric (n=1,440) cancer. The Kaplan-Meier estimator, independently described by Edward Kaplan and Paul Meier and conjointly published in 1958 in the Journal of the American Statistical Association, is a non-parametric statistic that allows us to estimate the survival function. K aplan-Meier curves are widely used in clinical and fundamental research, but there are some important pitfalls to keep in mind when making or interpreting them.
