The problem did not occur when both sample sizes were identical.įixed a problem in calculating the effect size from variances in the repeated measures ANOVA.
#GPOWER STACKABLE MAC#
20 August 2012 - Release 3.1.5 Mac and Windowsįixed a problem in the test of equality of two variances. The drawers now appear correctly after clicking on the Determine button. 12 September 2012 - Release 3.1.5.1 Macįixed a problem with the effect size drawers of ANOVA: Fixed effects. Macįixed a problem in Fisher’s exact test. 18 Frebruary 2013 - Release 3.1.6 Mac and Windowsįixed a problem in the sensitivity analysis of the logistic regression. 19 April 2013 - Release 3.1.7 Mac and Windowsįixed a problem in the exact test of Proportions: Inequality, two independent groups (uncontional). Improvements in the logistic regression module: (1) improved numerical stability (in particular for lognormal distributed covariates) (2) additional validity checks for input parameters (this applies also to the poisson regression module) (3) in sensitivity analyses the handling of cases in which the power does not increase monotonically with effect size is improved: an additional Actual power output field has been added a deviation of this actual power value from the one requested on the input side indicates such cases it is recommended that you check how the power depends on the effect size in the plot window.
#GPOWER STACKABLE WINDOWS#
31 January 2014 - Release 3.1.8 Mac and Windows Note, however, that the change affects the results only when N is very small. Negative effect directions, that is, slope|H1 = upper limit. 6 February 2019 - Release 3.1.9.4 Mac and Windowsįixed a bug in t tests: Linear bivariate regression: One group, size of slope. 14 January 2020 - Release 3.1.9.5 Macįixed a bug that caused the “Options” button (which is available for some tests in the main window) to disappear when “Hide distributions & control” was selected. 21 February 2020 - Release 3.1.9.6 Mac and Windowsįixed a bug in z tests: Generic z test: Analysis: Criterion: Compute alpha: The critical z was calculated incorrectly.įixed a bug in t tests: Linear bivariate regression: One group, size of slope: |sy/sx| was sometimes calculated inccorrecty.
#GPOWER STACKABLE UPDATE#
The new Sony 10-20mm F4 is still more compact compared to this APS-C lens even with 2mm longer reach (the 10-18mm has a built in Image Stabilization / OSS ).Changed the behavior of the “X-Y plot for a range of values” which allowed plotting graphs after changing input parameters in the main window without hitting the “Calculate” button which, however, is required to update the “X-Y plot for a range of values” with the new input parameters from the main dialog. If you think the size comparison of and APS-C lens vs a FF lens is not fair, here we have a comparison with another APS-C lens, the previous Wideangle Zoom lens for the E-mount, Sony E 10-18mm F4 OSS. Read our detailed comparison of these two lenses here.īonus Comparison: Sony 10-20mm F4 PZ G vs Sony 10-18mm F4 OSS Sony E 10-20mm F4 PZ G vs Sony 16-35mm F4 PZ G Power Zoom Lens Comparison
#GPOWER STACKABLE FULL#
Besides the full frame coverage vs APS-C coverage, the biggest advantage of the 16-35mm is the inclusion of an Aperture ring on the body whereas with the 10-20mm, you rely solely on the external controls on the camera body. Here is a quick comparison of specs and features of the two lenses. Sony A6600 vs A7C Top View Size Comparison The 10-20mm F4 PZ G with a APS-C Sony camera such a Sony Alpha a6600 will be much smaller and lighter than a 16-35mm F4 PZ G with a compact FF camera such as the Sony Alpha A7c. It is also 11mm narrower and 33mm shorter the larger FF lens.
The 10-20mm F4 with a weight of 178g is almost half the weight of the 16-35mm F4. Here is a size comparison which shows how impressively compact the new 10-20mm is, especially considering that the 16-35mm F4 G PZ is no slouch, quite compact for its class. Both lenses are Power Zoom lenses and have similar focal coverages.The 10-20mm has a full frame equivalent focal range of 15-30mm which is 1mm wider on the wide end but 5mm shorter at the tele end but these are still in very comparable range. Spec and focal range wise, this new lens looks so much like another Sony lens that was recently released, the Sony FE PZ 16-35mm F4 G which has a full frame coverage. Sony surprised the camera world and released 3 new APS-C lens for its E mount, 2 Wideangle primes and 1 Wideangle Zoom.For most users, the Sony E 10-20mm F4 PZ G Power Zoom lens is probably the most exciting lens out of the three, specially designed for videography in mind.
