In the forum of JASP, I noticed that even in the recent version may get a NaN for Error%, which indicates that the t-value is really large (as the BF value) and that the Error% is really small (i.e., close to zero). Though, since the values are so close to 0 someone could report just an Errorr% ~0 (approx zero). XLSTAT is a powerful yet flexible Excel data analysis add-on that allows 150,000+ users in over 120 countries across the world to analyze, customize, and share results within Microsoft Excel. I received extremely small values of Error% (e.g., ~ 3.643e-24 ) instead of NaN. I tried the 0.11.1.0 version of JASP and the problem in my analyses is sorted. Nevertheless, the most recent version of JASP is able to calculate even smaller Error%. The correction factor is close to its maximum value, which might produce the problem." So, it is indeed due to the large BF and the specificity of the H1. The problem derives from "The one-sided BF is calculated by departing from the two-sided BF and then adding a correcting factor. The problem was clearly the software (JASP) and not the analyses. Human Factors in Computing Systems (CHI '11). The aligned rank transform for nonparametric factorial analyses O., Findlater, L., Gergle, D., and Higgins, J. Summary.art and a warning generated if the F values are notĪn object of class "anova", which usually is printed. If that is not theĬase, another analysis should be considered. If the ART procedure is appropriate for this data, these tests should haveĪll effects "stripped out", and have an F value of ~0. When response is "aligned", all rows except the rowĬorresponding to the fixed effect term the response was aligned by are kept. Significance for the effect of each term on the original response variable. These results represent nonparametric tests of When response is "art" (the default), only one row is keptįrom each ANOVA: the row corresponding to fixed effect term the response wasĪligned and ranked by.

In addition to degrees of freedom are printed in some ANOVA types (e.g. When TRUE, sums of squares and residual sum of squares ( FALSE), shows only the rows that are relevant depending on the type Show all rows of the resulting ANOVA tables? By default average rank for each of the k seasonal groups should be similar and also. sum-to-zero contrasts, which is appropriate for Comparison of decision thresholds calculated from log-transformed background. Like most non-parametric tests, you perform it on ranked data, so you convert the measurement observations to their ranks in the overall data set: the smallest value gets a rank of 1, the next smallest gets a rank of 2, and so on. As consequence the ANOVA may result in a. That is, you lose completely the distance between data. The name of the contrast-generating function to beĪpplied by default to fixed effect factors. When you transform numeric data to ranks you distortion the metric space of your data. ![]() ![]() Modelsįit with Error terms are fit using aov, which only ![]() The default is Type III if the underlying model supports it.
