Introduction
Leora Software Polo Plus is a software package that consists of four statistical modules: PoloPC, PoloMix, PoloEncore, and PoloDose. These modules allow you to perform various types of analyses on quantal response data, such as dose-response curves, mixture toxicity tests, time-mortality data, and dose-number responses. You can also use the software to calculate confidence intervals, compare treatments, test hypotheses, and estimate parameters.
Quantal response bioassays are experiments that measure the effects of different doses or concentrations of a substance on living organisms. For example, you might want to know how much pesticide is needed to kill 50% of a population of insects, or how much drug is required to cure 90% of a group of patients. These types of experiments are widely used in fields such as toxicology, pharmacology, epidemiology, and ecology.
Leora Software Polo Plus is useful for analyzing quantal response bioassays because it offers several advantages over other methods or software. For instance, it can handle complex data sets with missing values, censored observations, or multiple responses. It can also deal with non-linear models, interactions, heterogeneity, and variability. Moreover, it can produce graphical outputs that help you visualize your data and results.
Leora Software Polo Plus is not free software. It normally costs $295 to purchase from the developer's website[^ However, there are some ways to get Leora Software Polo Plus for free. In the next section, we will show you three methods that you can try to get this software without paying a dime. Keep reading to learn more.
Features of Leora Software Polo Plus
Before we tell you how to get Leora Software Polo Plus for free, let's take a look at some of the features that make this software so powerful and useful. Here are some of the main features of Leora Software Polo Plus:
Four statistical modules in one software package
Leora Software Polo Plus includes four statistical modules that allow you to perform different types of analyses on quantal response data. These modules are:
PoloPC: This module is designed for analyzing dose-response data using probit or logit regression models. You can use it to fit various types of curves, such as linear, quadratic, cubic, exponential, logistic, or Weibull. You can also use it to calculate lethal doses (LD), effective doses (ED), or inhibition doses (ID) for any percentage of response. You can also compare the slopes, intercepts, or potencies of different treatments or groups.
PoloMix: This module is designed for analyzing mixture toxicity data using probit or logit regression models. You can use it to test the effects of different combinations of substances on living organisms. You can also use it to estimate the joint action of the mixture components, such as additive, synergistic, or antagonistic. You can also compare the toxicity of different mixtures or components.
PoloEncore: This module is designed for analyzing time-mortality data using probit or logit regression models. You can use it to fit various types of survival curves, such as exponential, Weibull, log-logistic, or log-normal. You can also use it to calculate lethal times (LT), effective times (ET), or inhibition times (IT) for any percentage of mortality. You can also compare the rates, durations, or efficacies of different treatments or groups.
PoloDose: This module is designed for analyzing dose-number data using probit or logit regression models. You can use it to fit various types of dose-number curves, such as linear, quadratic, cubic, exponential, logistic, or Weibull. You can also use it to calculate the number of organisms affected by a given dose, or the dose required to affect a given number of organisms. You can also compare the sensitivities, resistances, or tolerances of different treatments or groups.
With these four modules, you can perform a wide range of analyses on quantal response data with ease and accuracy.
State of the art charting features
Leora Software Polo Plus also offers state of the art charting features that help you visualize your data and results. You can create various types of charts, such as scatter plots, line graphs, bar charts, pie charts, box plots, or histograms. You can also customize your charts with different colors, fonts, symbols, legends, titles, axes, scales, grids, or labels. You can also export your charts as image files in various formats, such as BMP, JPG, PNG, GIF, or TIF.
Here is an example of a chart created by Leora Software Polo Plus:
This chart shows the dose-response curve for a pesticide on insects. The x-axis shows the dose in ppm (parts per million), and the y-axis shows the percentage of mortality. The blue dots represent the observed data points, and the red line represents the fitted curve using a probit model. The green lines represent the 95% confidence intervals for the curve. The chart also shows the LD50 value (the dose that kills 50% of the insects) and its 95% confidence interval.
With these charting features, you can present your data and results in a clear and attractive way.
User-friendly interface and help file
Leora Software Polo Plus also has a user-friendly interface and help file that make it easy to navigate and use the software. The interface consists of menus, toolbars, tabs, buttons , and windows that allow you to access and control the various functions and options of the software. The interface is intuitive and simple, so you can easily find what you need and perform your tasks quickly and efficiently. The interface also supports multiple languages, such as English, Spanish, French, German, Italian, Portuguese, or Chinese.
The help file is a comprehensive and detailed guide that explains how to use the software and its features. The help file covers topics such as installation, activation, data entry, data analysis, data output, charting, troubleshooting, and more. The help file also provides examples, screenshots, formulas, references, and glossary to help you understand the concepts and methods involved in the software. You can access the help file from the menu bar or by pressing F1 on your keyboard.
With these user-friendly features, you can learn and use the software without any difficulty or confusion.

The first method is to download the software from the developer's website. The developer offers a free trial version of the software that you can download and use for 30 days. The trial version has all the features and functions of the full version, except that it limits the number of data points that you can enter or analyze. For example, you can only enter up to 10 data points for PoloPC, 5 data points for PoloMix, 20 data points for PoloEncore, and 15 data points for PoloDose. However, this should be enough for you to test the software and see if it meets your needs and expectations.
To download the trial version of the software, you need to fill out a form on the developer's website with your name, email address, country , and how you heard about the software. You also need to agree to the terms and conditions of the software. After you submit the form, you will receive an email with a link to download the trial version of the software. You can then install and run the software on your Windows device. You can use the trial version for 30 days, after which it will expire and stop working. If you want to continue using the software, you need to purchase the full version from the developer's website.

Use a USB drive
The second method is to use a USB drive. The developer also offers a USB version of the software that you can purchase for $295. The USB version has all the features and functions of the full version, and it does not limit the number of data points that you can enter or analyze. The USB version also does not require installation or activation, and it can run on any Windows device that has a USB port. You can use the USB version as long as you have the USB drive plugged into your device.
However, if you do not want to buy the USB version, you can still use it for free if you know someone who has it. You can borrow their USB drive and plug it into your device, and then run the software from the USB drive. You can use the software as long as you have the USB drive plugged into your device, and as long as the owner of the USB drive allows you to use it.
